Active production — still a design-in option
The TPS77101DGK: ROHS3 compliant, which clears the EU regulatory gate without an exemption expiry to track.
150 mA adjustable rail — the fit decision
The positive output configuration and single regulator topology mean it is a straightforward drop-in for a point-of-load rail that needs better noise rejection than a switching converter can deliver alone.
60 dB of power-supply rejection at 1 kHz means the regulator attenuates upstream ripple by a factor of 1000 at that frequency — relevant when the input comes from a switching converter whose fundamental switching noise sits in the 100 kHz to 2 MHz range, where PSRR typically rolls off.
125 µA quiescent current and protection set
Built-in over-current, over-temperature, and reverse polarity protection mean the part survives a miswired bench test or a brief output short without latching off — the thermal shutdown resets when the junction cools below the threshold.
