MIC5367/8
High Performance 200mA Peak LDO
in 1.6mm x 1.6mm Thin MLF^®
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.
