The MIC5265 from Micrel Semiconductor is a 150mA ?Cap LDO regulator with a 2.7V to 5.5V input operating voltage range, making it suitable for operation from a single cell Li-ion battery or fixed 3.3V and 5V systems. According to the company, its new product is designed for applications where cost is the priority, including RF and digital applications.

The new LDO regulator offers low dropout voltage (210mV at 150mA), low noise (57?Vrms), high PSRR and integrates an active shutdown circuit on the output of each regulator to discharge the output voltage when disabled.

Offered in Pb-free Thin SOT-23-5 packaging, the MIC5265 comes with an enable pin and can be put into a zero off-mode current state. With good output noise and high PSRR, the MIC5265 is ideal for noise sensitive applications such as RF; while the fast transient response and active shutdown circuitry makes it well-suited for powering digital circuitry.
