MIC5301 Single, 150mA Cap ULDO General Description Features The MIC5301 is a high performance, single output Ultra low dropout voltage 40mV 150mA ultra low LDO (ULDO) regulator, offering low total Input voltage range: 2.3V to 5.5V output noise. The MIC5301 is capable of sourcing 150mA guaranteed output current 150mA output current and offers high PSRR and low Stable with ceramic output capacitors output noise, making it an ideal solution for RF applications. Ultra low output noise 30Vrms Low quiescent current 85A total For battery operated applications, the MIC5301 offers 2% accuracy, extremely low dropout voltage (40mV High PSRR up to 75dB 1kHz 150mA), and low ground current (typically 85A total). 35s turn-on time The MIC5301 can also be put into a zero-off-mode High output accuracy current state, drawing no current when disabled. 2% initial accuracy The MIC5301 is available in the 1.6mm x 1.6mm Thin 2 3% over temperature MLF package, occupying only 2.56mm of PCB area, a 36% reduction in board area compared to SC-70 Thermal shutdown and current limit protection and 2mm x 2mm MLF packages. Tiny 6-pin 1.6mm x 1.6mm Thin MLF leadless The MIC5301 has an operating junction temperature package range of 40C to +125C and is available in fixed and Thin SOT-23-5 package adjustable output voltages in lead-free (RoHS compliant) Thin MLF and Thin SOT-23-5 packages.
