MIC5387 Datasheet, PDF (1/12 Pages) Micrel Semiconductor – Ultra-Small Triple 150mA Output LDO

MIC5387
Ultra-Small Triple 150mA Output LDO
General Description
The MIC5387 is an advanced, general-purpose, triple
linear regulator offering high power supply rejection
(PSRR) in an ultra-small, 6-pin, 1.6mm x 1.6mm Thin
MLF^® package. The MIC5387 is capable of 150mA from
each output and offers high PSRR, making it an ideal
solution for any portable electronic application.
Ideal for battery powered applications, the MIC5387 offers
2% initial accuracy, low dropout voltage (180mV @
150mA), and low ground current (typically 32µA per
output).
The MIC5387 is available in a lead-free (RoHS compliant)
1.6mm x 1.6mm 6-pin Thin MLF^® occupying only 2.56mm²
of PCB area, a 36% reduction in board area compared to a
2mm x 2mm Thin MLF^® package.
The MIC5387 has an operating junction temperature range
of −40°C to +125°C.
