The MIC5264 is a dual 150mA LDO in tiny 2.5mm x
2.5mm MLF packaging ideal for applications where cost
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.
