MIC5265 150mA Cap LDO Regulator General Description Features The MIC5265 is a 150mA LDO in lead-free Thin SOT-23-5 2.7V to 5.5V supply voltage. packaging ideal for applications where cost is the priority. Low 75A quiescent current per LDO. The MIC5265 is ideal for any application in portable Thin SOT-23-5 package. electronics, including both RF and Digital applications. Low Noise 57Vrms. With low output noise and high PSRR, the MIC5265 is ideal for noise sensitive applications such as RF. While the High PSRR 60dB at 1kHz. fast transient response and active shutdown circuitry Low dropout voltage 210mV at 150mA. makes it well-suited for powering digital circuitry. Stable with ceramic output capacitors. The MIC5265 has a 2.7V to 5.5V input operating voltage Fast transient response. range, making it ideal for operation from a single cell Active shutdown. lithium ion battery or fixed 3.3V and 5V systems. The MIC5265 come with an enable pin and can be put into a Applications zero off-mode current state. The MIC5265 offers low dropout voltage (210mV at Cellular Telephones 150mA), low output noise (57Vrms), high PSRR and PDAs integrates an active shutdown circuit on the output of each GPS Receivers regulator to discharge the output voltage when disabled.
