MIC5252

150mA High PSRR, Low Noise

Cap CMOS LDO

General Description

The MIC5252 is an efficient, precise CMOS voltage regulator

optimized for ultra-low-noise applications. It offers 1% initial

accuracy, extremely-low dropout voltage (135mV at 150mA)

and low ground current (typically 90µA). The MIC5252 pro-

vides a very-low-noise output, ideal for RF applications

where a clean voltage source is required. The MIC5252 has

a high PSRR even at low supply voltages, critical for battery

operated electronics. A noise bypass pin is also available for

further reduction of output noise.

Designed specifically for handheld and battery-powered de-

vices, the MIC5252 provides a TTL-logic-compatible enable

pin. When disabled, power consumption drops nearly to zero.

The MIC5252 also works with low-ESR ceramic capacitors,

reducing the amount of board space necessary for power

applications, critical in handheld wireless devices.

Key features include current limit, thermal shutdown, faster

transient response, and an active clamp to speed up device

turn-off. The MIC5252 is available in the 6-pin 2mm

2mm

MLF™ package and the IttyBitty® SOT-23-5 package in a

wide range of output voltages.
