MIC5323

High PSRR Low Noise 300mA µCap

Ultra-Low Dropout LDO Regulator

General Description

The MIC5323 is a high-performance, 300mA LDO regula-

tor, offering extremely high PSRR and very low noise while

consuming low ground current.

Ideal for battery operated applications, the MIC5323

features 2% accuracy, extremely low dropout voltage

(120mV @ 300mA), and low ground current at light load

(typically 90µA). When disabled, the MIC5323 typically

consumes less than 1µA.

The MIC5323 is a µCap design operating with small

ceramic output capacitors for stability, thereby reducing

required board space and component cost.

The MIC5323 is available in

ﬁxed

output voltages and

adjustable output voltages in the super compact

6-pin 2mm × 2mm Thin MLF

and thin SOT-23-5 package.

Additional voltage options are available. Contact Micrel

marketing.
