Product details

Dual 150 mA LDO with 0.1 V dropout

The Micrel MIC5310-PKYML is a dual-output low-dropout linear regulator delivering 150 mA per channel from fixed output voltages of 2.6 V and 3.0 V. Maximum dropout is 0.1 V at the full 150 mA load, which means the input rail can sit as low as 2.7 V for the 2.6 V output and still maintain regulation — a tight headroom budget that matters when the supply is a 3.3 V or 5 V rail already loaded with other devices. The 120 µA quiescent current per regulator (190 µA max supply current for both channels) keeps the standing power low in battery-powered or always-on systems.

PSRR across the audio band

Power-supply rejection ratio is 70 dB at 1 kHz and 65 dB at 20 kHz.

Frequently asked questions
