Microchip Technology MIC5301-1.8YMT-TR

Description
The MIC5301 is a high-performance, single-output ultra-low LDO (ULDO™) regulator with low total output noise. It can source 150mA output current and offers high PSRR and low output noise, making it suitable for RF applications.
For battery-operated applications, the MIC5301 provides 2% accuracy, extremely low dropout voltage (40mV @ 150mA), and low ground current (typically 85µA total). It can also be put into a zero-off-mode current state, drawing no current when disabled.
The MIC5301 is available in a 1.6mm x 1.6mm ThinMLF package, occupying only 2.56mm² of PCB area, a 36% reduction compared to SC-70 and 2mm x 2mm MLF packages. It 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.
