MICROCHIP MIC5309YD6-TR

The MIC5309 is a high performance, HCap low dropout regulator, offering ultra-low operating current while maintaining very fast transient response. The MIC5309 can source up to 300mA of output current and can regulate down from a low input supply voltage to increase system efficiency. Ideal for battery operated applications; the MIC5309 offers extremely low dropout voltage 100mV typically @300mA load, and low ground current at all load conditions (typically 23μA). The MIC5309 can also be put into a zero-off-mode current state, drawing virtually no current when disabled. The MIC5309 is available in fixed output voltages in the tiny 6-pin 1.6mm x 1.6mm thin MLF leadless package as well as the 6-pin TSOT-23 for cost sensitive applications.
