MIC5265
150mA µCap LDO Regulator
General 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. 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 (57µVrms), high PSRR and
integrates an active shutdown circuit on the output of each
regulator to discharge the output voltage when disabled.
