General Description

The MIC5365/6 is an advanced general purpose linear

regulator offering high power supply rejection (PSRR) in

an ultra-small 1mm x 1mm package. The MIC5366

includes an auto-discharge feature that is activated when

the enable pin is low. The MIC5365/6 is capable of

sourcing 150mA output current and offers high PSRR

making it an ideal solution for any portable electronic

application.

Ideal for battery-powered applications, the MIC5365/6

offers 2% initial accuracy, low dropout voltage (155mV @

150mA), and low ground current (typically 29µA). The

MIC5365/6 can also be put into a zero-off-mode current

state, drawing virtually no current when disabled.

The MIC5365/6 is available in several advanced packages

including a lead-free (RoHS-compliant) 1mm x 1mm Thin

MLF

® occupying only 1mm2 of PCB area, a 75% reduction

in board area compared to SC-70 and 2mm x 2mm MLF

®

packages. It is also available in a thin SOT23-5 package.

The MIC5365/6 has an operating junction temperature

range of –40°C to 125°C.
