General Description

The MIC5264 is a dual 150mA LDO in tiny 2.5mm x

2.5mm MLF

is the priority. The MIC5264 is ideal for any application in

portable electronics, including both RF and Digital

applications. With low output noise and high PSRR, the

MIC5264 is ideal for noise sensitive RF applications. While

the fast transient response and active shutdown circuitry

makes it well-suited for powering digital circuitry.

The MIC5264 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. Each

LDO is completely independent and can be powered

independently, making it easier to use in distributed power

applications.

The MIC5264 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.
