MIC5301

Single, 150mA µCap ULDO™

General Description

Features

The MIC5301 is a high performance, single output

ultra low LDO (ULDO™) regulator, offering low total

output noise. The MIC5301 is capable of sourcing

150mA output current and offers high PSRR and low

output noise, making it an ideal solution for RF

applications.

• Ultra low dropout voltage – 40mV @ 150mA

• Input voltage range: 2.3V to 5.5V

• 150mA guaranteed output current

• Stable with ceramic output capacitors

• Ultra low output noise – 30µVrms

• Low quiescent current – 85µA total

• High PSRR – up to 75dB@1kHz

• 35µs turn-on time

For battery operated applications, the MIC5301 offers

2% accuracy, extremely low dropout voltage (40mV @

150mA), and low ground current (typically 85µA total).

The MIC5301 can also be put into a zero-off-mode

current state, drawing no current when disabled.

• High output accuracy

• ± 2% initial accuracy

• ± 3% over temperature

The MIC5301 is available in the 1.6mm x 1.6mm Thin

MLF^®package, occupying only 2.56mm²of PCB area,

a 36% reduction in board area compared to SC-70

and 2mm x 2mm MLF^®packages.

• Thermal shutdown and current limit protection

• Tiny 6-pin 1.6mm x 1.6mm Thin MLF^®leadless

The MIC5301 has an operating junction temperature

range of –40°C to +125°C and is available in fixed and

adjustable output voltages in lead-free (RoHS

compliant) Thin MLF^®and Thin SOT-23-5 packages.
