General Description

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

6-pin 2mm × 2mm Thin MLF

Additional voltage options are available. Contact Micrel

marketing.
