MICROCHIP MIC5232-1.8YD5-TR

The MIC5232 is an ultra-low quiescent current, lowdropout linear regulator that is capable of operating from a single-cell lithium ion battery. Consuming only 1.8 μA 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 (V_OUT > V_IN) down to 20nA. The MIC5232 is a uCap 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 2 mm × 2 mm MLF* package and thin SOT-23-5 package with an operating junction temperature range of -40 ℃ to 125 ℃.
