MIC5232-3.3YD5

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.
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 (VOUT > VIN) down to 20nA.
The MIC5232 is a µCap design, operating with very small ceramic output capacitors for stability, reduction of required board space and component cost.
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.
