Microchip | MIC5318-2.8YMT-TR

The MIC5318 is a high performance, single output ultra low drop-out (ULDO™) regulator, offering low total output noise in an ultra-small Thin MLF ® package. The MIC5318 is capable of sourcing 300 mA output current and offers high PSRR and low output noise, making it an ideal solution for RF applications.

The MIC5318 offers 2% initial accuracy, extremely low dropout voltage (110 mV @ 300 mA), and low ground current (typically 85 µA total). The MIC5318 can also be put into a zero-off-mode current state, drawing no current when disabled.

The MIC5318 is available in the 1.6 mm x 1.6 mm Thin MLF ® package, occupying only 2.56 mm 2 of PCB area, fully a 36% reduction in board area when compared to SC-70 and 2 mm x 2 mm MLF ® packages. The MIC5318 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 SOT23-5 packages.
