Microchip | MIC5305-2.85YD5-TR

The MIC5305-2.85YD5 TR is a high-performance, 150 mA LDO regula-tor, offering extremely high PSRR and very low noise while consuming low ground current.

The MIC5305 features 1% accuracy, extremely low-dropout voltage (60 mV @ 150 mA), and low ground current at light load (typically 90 µA). 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. The MIC5305 is available in thin SOT-23-5 package.
