AS13986

Dual Low-Noise, Low-Dropout Voltage Regulator
1 General Description

The AS13986 dual low-dropout regulator provides up to 150mA at each output using a to 5.5V input voltage. The ultra-low drop-out voltage, low quiescent current, and low noise make the AS13986 perfect for low-power, battery-operated applications.

Regulator ground current increases only slightly in dropout, extending the battery life in low-power applications.

The device features excellent power supply rejection 55dB 1kHz and 50dB at 10kHz . The high power supply rejection is maintained down to low input voltage levels used in battery operated devices.

Integrated shutdown logic control function is available for each output. In cases where the device is used as a local regulator it is possible to switch some of the circuitry into standby mode, thus decreasing total power consumption.

The AS13986 was specifically designed to work with low-ESR ceramic capacitors.

The AS13986 is available in a 8-pin WLP package.
