Fixed 2.7 V LDO with 28 µA quiescent current
The Texas Instruments TPS76927DBVT is a positive-output, fixed 2.7 V linear regulator delivering up to 100 mA. The SOT-23-5 (SC-74A) package suits compact PCB layouts where board area is constrained.
PSRR and protection features
Power-supply rejection ratio is 60 dB at 1 kHz, meaning the regulator attenuates upstream ripple by a factor of 1000 at that frequency — useful for powering analog front-ends or noise-sensitive loads from a switching pre-regulator. Built-in protection includes over-current, over-temperature, and reverse polarity. The enable pin (active-high) allows the output to be gated by a logic signal for sequenced power-up or shutdown.
