Product details

Ripple Blocker — PSRR bandwidth and the 2.8 V rail

The MIC94310-MYMT-TR is a single-output, positive fixed-output LDO from Microchip's Ripple Blocker™ series, delivering 200 mA at 2.8 V from a 3.6 V max input rail. Its defining spec is the PSRR curve: 85 dB at 100 Hz rolling off to 50 dB at 10 MHz — this is not a generic LDO; it is designed to clean up switching noise from a downstream DC-DC converter or a noisy input bus, especially in the 100 kHz to 10 MHz band where many switchers radiate ripple. The 250 µA quiescent current is moderate; not ultra-low-power, but acceptable for always-on rails in industrial or automotive modules where the load current dominates the budget.

Package and thermal: 4-TDFN exposed pad

Control is via a single Enable pin; the part also integrates over-current and over-temperature protection.

Lifecycle and sourcing posture

ROHS3 compliant (EU Directive 2015/863).

Frequently asked questions

What is the PSRR of the MIC94310-MYMT-TR at 1 MHz?

The PSRR is specified as 85 dB at 100 Hz, rolling down to 50 dB at 10 MHz. At 1 MHz it falls between those endpoints — approximately 60–65 dB based on the typical curve, though the datasheet provides the exact frequency response. This means the LDO attenuates 1 MHz switching ripple by a factor of roughly 1000, which is sufficient to clean up a buck converter's output for a sensitive analog rail.
