General Description

The MIC5367/8 is an advanced general purpose linear

regulator offering high power supply rejection (PSRR) in

an ultra-small 1.6mm x 1.6mm package. The MIC5368

includes an auto-discharge feature that is activated when

the enable pin is low. The MIC5367/8 is capable of

sourcing 200mA peak (150mA continous) output current

and offers high PSRR making it an ideal solution for any

portable electronic application.

Ideal for battery powered applications, the MIC5367/8

offers 2% initial accuracy, low dropout voltage (180mV @

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

MIC5367/8 can also be put into a zero-off-mode current

state, drawing virtually no current when disabled.

The MIC5367/8 has an operating junction temperature

range of –40°C to 125°C.
