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

1.8

MIC5232 is ideal for stand-by applications like

powering real-time clocks or memory in battery

operated electronics.

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

The MIC5232 is a µCap design, operating with very

small ceramic output capacitors for stability, reducing

required board space and component cost.

The MIC5232 is available in fixed output voltages in

the miniature 6-pin 2mm x 2mm MLF

thin SOT-23-5 package with an operating junction

temperature range of -40°C to 125°C.
