.COM PRODUCTION DATASHEET LX8213 300mA Low Noise CMOS LDO Regulator KEY FEATURES The LX8213 LDO regulator is part of Microsemi’s family of positive voltage regulator ICs using CMOS technology. The device provides a compact and cost effective solution featuring low power consumption over a wide supply voltage range, high output voltage accuracy, low dropout, excellent line and load regulation, fast transient response, and low noise. The LX8213 operates over a wide input voltage range of 2.5V to 6V, and consumes only 60uA typical quiescent current at no load and a low 0.1uA shutdown current. Output voltage options include fixed 1.0V, 1.2V, 3.3V, or an adjustable output voltage which may be set from 800mV to 5.5V. The LDO delivers up to 300mA of output current, with a foldback current limit of approximately 400mA. At 300mA load, dropout voltage measures only 170mV for a 3.3V output. Tight load and line regulation is achieved over the full output current and supply range. The high bandwidth control loop provides fast transient response to reduce output voltage deviation using low cost external ceramic capacitors in the 1uF range. The LX8213 also exhibits low output noise with only 60uVRMS over a 100kHz bandwidth. Power supply rejection exceeds 65dB at 100Hz. Other features of LX8213 include an active low shutdown input with a internal pull-down for low cost power sequencing, internal soft-start circuitry to prevent inrush current, short circuit current limit, and thermal overload protection. The LX8213 operates over to ambient temperature range and is available in a tiny 5 pin SOT-23 ROHS compliant package. 2.5V to 6V Wide Input Voltage Range Fixed Output 1.0V, 1.2V, 3.3V, or 0.8V to 5.5V Adjustable Output Voltage Range Low Quiescent Current of Typical 60uA Low Dropout Voltage of Typical 170mV at 3.3V 300mA Stable with Low ESR 1uF Input/Output Bypass Ceramic Capacitors Ultra Low Shutdown Current of Typical 0.1uA Low Output Noise of Typical 60uVRMS at VOUT=0.8V Fast Transient Response Shutdown Control Input Foldback Current Limit 50mA Short Circuit Limit Over Temperature Protection Standard Package SOT-23 RoHS Compliant Battery Operated Systems Set-Top Box LCD TV’s Routers Video Cards Hand Held Instruments PACKAGE ORDER INFO TA °C Plastic SOT-23 5-pin RoHS Compliant / Pb-free -40 to +85 LX8213-00ISE Adjustable Marking “FAD” LX8213-10ISE 1.0V Fixed Output Marking “FAJ” LX8213-12ISE 1.2V Fixed Output Marking “FAK” LX8213-33ISE 3.3V Fixed Output Marking “FAL” Note Available in Tape & Reel.
