Microchip MIC5207-3.3YM5-TR, 1-Channel Low Dropout Voltage, Voltage Regulator, 180 mA, 5V, SOT-23 5-Pin

The Microchip Efficient linear voltage regulator with ultra-low-noise output, very low dropout voltage (typically 17mV at light loads and 165mV at 150mA), and very low ground current (720μA at 100mA output). It offers better than 3% initial accuracy. Designed especially for hand-held, battery-powered devices, It includes a CMOS or TTL compatible enable and shutdown control input. When in shutdown, power consumption drops nearly to zero.

• Ultra-low noise output
• High output voltage accuracy
• Guaranteed 180mA output
