DescriptionThe MIC5264 is a dual 150mA LDO in tiny 2.5mm x 2.5mm MLF
(TM) 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 (57Vrms), high PSRR and integrates an active shutdown circuit on the output of each regulator to discharge the output voltage when disabled.
