MIC5232

10mA Ultra-Low Quiescent Current

µCap LDO

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

Features

• Input voltage range: 2.7V to 7.0V

• Ultra-low Iq: Only 1.8 A operating current

• Stable with 0.47µF ceramic output capacitor

• Low dropout voltage of 100mV @ 10mA

• Reverse Battery Protection

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

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.

Including reverse current protection, keeping reverse

leakage (V_OUT> V_IN) down to 20nA.

• Logic-Level Enable Input

• Miniature 6-pin 2mm x 2mm MLF^®package

• Lead-Free Thin SOT-23-5 Package

• Tight Load and Line Regulation

The MIC5232 is a µCap design, operating with very

small ceramic output capacitors for stability, reducing

required board space and component cost.

Applications

• 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.
