Product details

What this adjustable LDO brings to a power rail

The Microchip MIC5353YMT-TR is a single-output positive adjustable LDO regulator delivering up to 500 mA from a 1.25 V to 5.5 V output range, with a maximum input of 6 V. Key features include an enable pin for shutdown control, over-current and over-temperature protection, and a quiescent current of 175 µA. The dropout voltage is specified at 0.35 V maximum at the full 500 mA load.

PSRR at 1 kHz — what 60 dB means for noise-sensitive rails

The MIC5353YMT-TR lists a power-supply rejection ratio of 60 dB at 1 kHz. That translates to roughly 1 mV of ripple on the output for every 1 V of ripple on the input at that frequency.

Package and footprint — 6-TMLF with exposed pad

The device is supplied in a 6-UFDFN exposed-pad package, also designated 6-TMLF, measuring 1.6x1.6 mm. Surface-mount assembly is standard; the Tape & Reel option (TR suffix) is the reeled variant for automated pick-and-place.

Frequently asked questions

What does the 60 dB PSRR at 1 kHz mean for my design?

A PSRR of 60 dB at 1 kHz means the output ripple is attenuated by a factor of 1000 relative to the input ripple at that frequency. For a typical 20 mVpp switching ripple on a 3.3 V input, the output sees about 20 µVpp of feedthrough — acceptable for most analog circuits, but if your ADC reference or sensor bias rail demands sub-10 µV noise, consider a higher-PSRR LDO or an additional LC filter stage.
