Microchip Technology MIC5305-2.5YD5-TR

Description
The MIC5305 is a high-performance, 150mA LDO regulator offering extremely high PSRR and very low noise while consuming low ground current. Ideal for battery-operated applications, the MIC5305 features 1% accuracy, extremely low-dropout voltage (60mV @ 150mA), and low ground current at light load (typically 90μA). Equipped with a logic-compatible enable pin, the MIC5305 can be put into a zero-off-mode current state, drawing no current when disabled. The MIC5305 is a μCap design operating with very small ceramic output capacitors for stability, thereby reducing required board space and component cost.
