MIC5385 Datasheet, PDF (1/13 Pages) Micrel Semiconductor – Ultra Small Triple 150mA Output LDO

MIC5385
Ultra Small Triple 150mA Output LDO
General Description
The MIC5385 is an advanced general purpose triple linear
regulator offering high power supply rejection (PSRR) in
an ultra-small 2mm x 2mm 8 pin Thin MLF^® package. The
MIC5385 is capable of sourcing 150mA for each output
and offers high PSRR making it an ideal solution for any
portable electronic application.
Ideal for battery powered applications, the MIC5385 offers
2% initial accuracy, low dropout voltage (180mV @
150mA), and low ground current (typically 32µA per
output). The MIC5385 can also be put into a zero-off-mode
current state, drawing virtually no current when disabled.
The MIC5385 is available in a lead-free (RoHS compliant)
2mm x 2mm 8 pin Thin MLF^® occupying only 4mm² of
PCB area, a 33% reduction in board area compared to a
3mm x 2mm Thin MLF^® package.
The MIC5385 has an operating junction temperature range
of –40°C to 125°C.
