... 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. The MIC5265 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 (57µ ...
