Microchip | MIC5301YD5-TR

The MIC5301YD5 TR is a high performance, single output ultra low LDO (ULDO™) regulator, offering low total output noise. The MIC5301 is capable of sourcing 150 mA 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 (40 mV @ 150 mA), and low ground current (typically 85 μA 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 1.6 mm x 1.6 mm Thin MLF® package, occupying only 2.56 mm2 of PCB area, a 36% reduction in board area compared to SC-70 and 2 mm x 2 mm 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.
