Features & Applications

The MIC5305-2.85YML 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 fixed output voltages and adjustable output voltages in the super-compact 6-pin 2 mm × 2 mm MLF ® leadless package.
