Datasheet AS1371 400mA, Low Input Voltage, Low Quiescent Current LDO 1 General Description The AS1371 low input voltage, positive voltage regulator is designed to deliver up to 400mA while consuming typically only 15µA of quiescent current. The device operates from input voltages of 1.2V to 3.6V, and is available in fixed output voltages between 0.6V and 3.3V programmable in 50mV steps . Operation at the full 400mA load current is dependent upon the maximum power dissipation available from package and environment. The low input voltage and ultra-low dropout voltage 20mV 100mA load and 80mV 400mA load supports single primary cell operation in small applications, when operated with minimum inputto-output voltage differentials. In addition, the regulator provides a power management life extension by operating from pre-existing 1.8V and 2.5V outputs to provide low output voltages for new generation portable processor cores. The device features stable output voltage with ceramic capacitors down to a value of 1µF, strict output voltage regulation tolerances ±1% , and good line- and load-regulation. The AS1371 is available in a 6-pin 2x2 TDFN package and is qualified for -40°C to +85°C operation.

All devices come with fixed output voltage from 0.6V to 3.3V. See Ordering Information on page The AS1371 also features a Power-OK output to indicate when the output is within 10% max of final value when the Enable pin is grounded. When the Enable pin is raised above ground, the POK comparator inputs are switched to change the functionality. The comparator reference is now 800mV and the Enable pin becomes an uncommitted comparator input. See Power-OK and Low-Battery-Detect Functionality page 9 for setting resistor values when monitoring other voltages i.e. VOUT . Shutdown current for the whole regulator is typically 10nA. The device features integrated short-circuit and over current protection. Under-Voltage lockout prevents erratic operation when the input voltage is slowly decaying e.g. in a battery powered application . Thermal Protection shuts down the device when die temperature reaches 150°C. This is a useful protection when the device is under sustained short circuit conditions. Figure 13 shows the block diagram of the AS1371. It identifies the basics of a series linear regulator employing a P-Channel MOSFET as the control element. A stable voltage reference REF in Figure 13 is compared with an attenuated sample of the output voltage. Any difference between the two voltages reference and sample creates an output from the error amplifier that drives the series control element to reduce the difference to a minimum. The error amplifier incorporates additional buffering to drive the relatively large gate capacitance of the series pass Pchannel MOSFET, especially under transient conditions, when additional drive current is required. Input supply variations are absorbed by the series element, and output voltage variations with loading are absorbed by the low output impedance of the regulator.

For more information contact: 8 - 17 AS1371 Datasheet - Detailed Description Power-OK and Low-Battery-Detect Functionality The AS1371’s power-ok or low-battery-detect circuitry is built around an N-channel MOSFET. The circuitry monitors the voltage on pin SENSE and if the voltage goes out of regulation e.g. during dropout, current limit or thermal shutdown the pin POK goes low. The pin SENSE can be connected to a resistive-divider to monitor a particular definable voltage and compare it with an internal voltage reference. If the SENSE pin is connected to GND an internal resistive-divider is activated and connected to the output. Therefore, the Power-OK functionality can be realized with no additional external components. The Power-OK feature is not active during shutdown and provides a power-on-reset function that can operate down to VIN = 1.2V. A capacitor to GND may be added to generate a power-on-reset delay. To obtain a logic-level output, connect a pull-up resistor from pin POK to pin OUT. Larger values for this resistor will help to minimize current consumption a resistor is perfect for most applications see Figure 1 on page For the circuit shown in the left of Figure 14 on page 9, the input bias current into SENSE is very low, permitting large-value resistor-divider networks while maintaining accuracy. Place the resistor-divider network as close to the device as possible. Use a defined resistor for R2 and then calculate R1 as: -----V----I--N------VSENSE Where: VSENSE = 800mV ± 150mV. In case of the SENSE pin is connected to GND, an internal resistor-divider network is activated and compares the output voltage with a 94% typ. voltage threshold. For this particular Power-OK application, no external resistive components are necessary.

The circuitry monitors and controls the gate voltage of the P-channel MOSFET, limiting the output current to 400mA. The P-channel MOSFET output can be shorted to ground for an indefinite period of time without damaging the device. Thermal-Overload Protection The devices are protected against thermal runaway conditions by the integrated thermal sensor circuitry. Thermal shutdown is an effective instrument to prevent die overheating since the power transistor is the principle heat source in the device. If the junction temperature exceeds 150ºC with 15ºC hysteresis, the thermal sensor starts the shutdown logic, at which point the P-channel MOSFET is switched off. After the device temperature has dropped by approximately 15ºC, the thermal sensor will turn the P-channel MOSFET on again. Note that this will be exhibited as a pulsed output under continuous thermal-overload conditions. 9 - 17 AS1371 Datasheet - Application Information 9 Application Information Dropout Voltage Dropout is the input to output voltage difference, below which the linear regulator ceases to regulate. At this point, the output voltage change follows the input voltage change. Dropout voltage may be measured at different currents and, in particular at the regulator maximum one. From this is obtained the MOSFET maximum series resistance over temperature etc. More generally: VDROPOUT = ILOAD RSERIES Dropout is probably the most important specification when the regulator is used in a battery application. The dropout performance of the regulator defines the useful “end of life” of the battery before replacement or re-charge is required.
