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 fea- tures 1% accuracy, extremely low-dropout voltage (60mV @ 150mA), and low ground current at light load (typically 90 µ A). 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  µ Cap 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 adjust- able output voltages in the super-compact 2mm  *  2mm MLF™-6 leadless package and thin SOT-23-5 package. Additional voltage options are available. Contact Micrel marketing.
