Product details

What this adjustable LDO brings to the rail

PSRR sits at 60 dB at 1 kHz — moderate rejection that cleans up switching-regulator ripple but won't compete with a high-PSRR LDO for sensitive analog front-ends. The quiescent current of 225 µA and max supply current of 325 µA keep the part efficient for always-on or battery-backed rails. Protection covers over-current, over-temperature, reverse polarity, and UVLO, so it survives a miswired bench or a hot reflow cycle.

The SOT-223-6 package is a tabbed surface-mount part with moderate thermal mass. Rework with hot air is doable if the board has enough preheat; the tab can act as a heat sink that makes the part stubborn to lift.

Frequently asked questions

Does TPS72501DCQ require external capacitors?

Yes, like most LDOs, the TPS72501DCQ needs input and output capacitors for stability. The datasheet specifies recommended values and ESR ranges — consult it for the exact selection for your output voltage and load.
