The MIC5305 is a high-performance, 150mA LDO regula-tor, 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.

The MIC5305 is available in fixed output voltages and adjustable output voltages in the super-compact 6-pin 2mm × 2mm MLF ® leadless package, our new ultra-thin
6-pin 2mm × 2mm Thin MLF ® and thin SOT-23-5 package. Additional voltage options are available. Contact Micrel marketing.
