Micrel 

MIC5301

Single, 150mA µCap ULDO™

General Description

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.

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.

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

MLF® package, occupying only 2.56mm2 of PCB area,

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

and 2mm x 2mm MLF® packages.

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.
