MIC5387 Triple Linear Regulators


Micrel's MIC5387 triple linear regulators have low dropout voltage


Micrel's MIC5387 is an advanced, general-purpose, triple linear regulator that offers 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 percent initial accuracy, low dropout voltage (180mV @ 150mA), and low ground current (typically 32μA per output).

This regulator occupies only 2.56mm2 of PCB area, which is a 36 percent reduction in board area compared to a 2mm x 2mm Thin MLF® package. The series has an operating junction temperature range of -40°C to 125°C. Datasheet
