MIC5305

In Production

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 at 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. ...
