Description

The MIC5265 is a 150mA LDO in lead-free Thin SOT-23-5 packaging ideal for applications where cost is the priority. 

The MIC5265 is ideal for any application in portable electronics, including both RF and Digital applications.  With low output noise and high PSRR, the MIC5265 is ideal for noise sensitive applications such as RF.  While the fast transient response and active shutdown circuitry makes it well-suited for powering digital circuitry.

The MIC5265 has a 2.7V to 5.5V input operating voltage range, making it ideal for operation from a single cell lithium ion battery or fixed 3.3V and 5V systems.  That come with an enable pin and can be put into a zero off-mode current state. 

The MIC5265 offers low dropout voltage (210mV at 150mA), low output noise (57Vrms), high PSRR and integrates an active shutdown circuit on the output of each regulator to discharge the output voltage when disabled.
