Microchip | MIC5308YMT-TR

The MIC5308 is a high performance, µCap low dropout regulator, offering ultra-low operating current while maintaining very fast transient response. The MIC5308 can source up to 150 mA of output current and can regulate down from a low input supply voltage to increase system efficiency.

The MIC5308 offers extremely low dropout voltage 45 mV typically @ 150 mA, and low ground current at all load conditions (typically 23 µA). The MIC5308 can also be put into a zero-off-mode current state, drawing virtually no current when disabled. The MIC5308 is available in fixed output voltages in the 6-pin TSOT-23 for cost sensitive applications.
