MIC5232

10mA Ultra-Low Quiescent Current

µCap LDO

Features

 Input voltage range: 2.7V to 7.0V

 Ultra-low Iq: Only 1.8µA operating current

 Stable with 0.47µF ceramic output capacitor

 Low dropout voltage of 100mV @ 10mA

 Reverse Battery Protection

General Description

The MIC5232 is an ultra-low quiescent current, low-

dropout linear regulator that is capable of operating

from a single-cell lithium ion battery. Consuming only

1.8µA of quiescent current while operating, the

MIC5232 is ideal for stand-by applications like

powering real-time clocks or memory in battery

operated electronics.

 High output accuracy:

– +2.0% initial accuracy

– +3.0% over temperature

 Logic-Level Enable Input

The MIC5232 is capable of providing 10mA of output

current and has low output noise, providing a small,

efficient solution ideal for any keep-alive application.

This includes reverse current protection, keeping

reverse leakage (V_OUT> V_IN) down to 20nA.

 Miniature 6-pin 2mm x 2mm MLF package

 Lead-Free Thin SOT-23-5 Package

 Tight Load and Line Regulation

Applications

The MIC5232 is a µCap design, operating with very

small ceramic output capacitors for stability, reduction

of required board space and component cost.

 Real-Time Clock Power Supply

 Stand-by Power Supply

 SRAM Memory Back-up Supply

 Cellular Telephones and Notebook Computers

The MIC5232 is available in fixed output voltages in

the miniature 6-pin 2mm x 2mm MLF^®package and

thin SOT-23-5 package with an operating junction

temperature range of -40°C to 125°C.
