MIC5264-SGYML-TR Microchip

MIC5264 150mA Cap Dual LDO Regulator General Description Features 2.7V to 5.5V supply voltage. The MIC5264 is a dual 150mA LDO in tiny 2.5mm x Low 75A quiescent current per LDO. 2.5mm MLF packaging ideal for applications where cost Tiny 2.5mm x 2.5mm MLF package. is the priority. The MIC5264 is ideal for any application in Low Noise 57Vrms. portable electronics, including both RF and Digital High PSRR 60dB at 1kHz. applications. With low output noise and high PSRR, the Low dropout voltage 210mV at 150mA. MIC5264 is ideal for noise sensitive RF applications. While Stable with ceramic output capacitors. the fast transient response and active shutdown circuitry makes it well-suited for powering digital circuitry. Independent enable pins. Fast transient response. The MIC5264 has a 2.7V to 5.5V input operating voltage Active shutdown on both outputs. range, making it ideal for operation from a single cell lithium ion battery or fixed 3.3V and 5V systems. Each Applications LDO is completely independent and can be powered Cellular Telephones independently, making it easier to use in distributed power PDAs applications. GPS Receivers 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.
