150mA fixed-output LDO in SOT-23-5
The TPS76316DBVR is a single-output, positive-voltage linear regulator from Texas Instruments, delivering a fixed 1.6V at up to 150mA. The SOT-23-5 (SC-74A) package suits space-constrained boards where a low-dropout rail is needed for a local 1.6V supply. Input voltage range extends to 10V maximum, and the 100µA typical quiescent current keeps the regulator's own draw low enough for always-on or battery-backed rails.
60dB PSRR at 1kHz and protection suite
Power-supply rejection ratio is 60dB at 1kHz — this attenuates 100mV of 1kHz ripple on the input to roughly 100µV at the output, relevant when the LDO sits downstream of a switching converter operating in that band. On-chip protection covers over-current, over-temperature, and reverse polarity. The enable pin allows external on/off control.
