MIC5305

150mA µCap Ultra-Low Dropout

LDO Regulator

General Description

Features

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

tor, offering extremely high PSRR and very low noise while

consuming low ground current.

• Ultra-low dropout voltage of 60mV @ 150mA

• Input voltage range: 2.25 to 5.5V

• Stable with ceramic output capacitor

• 150mA guaranteed output current

• Low output noise — 20µVrms

• Low quiescent current of 90µA total

• High PSRR, up to 85dB @1kHz

• Less than 30µs turn-on time w/C_BYP= 0.01µF

• High output accuracy:

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.
