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 2.56mm2 of 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.
