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 85A 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 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) MLF^® and Thin SOT-23-5 packages.
