Fixed 1.3V rail in a small SC-70-5
The SC-70-5 footprint is small enough for space-constrained PCBs. Operating temperature covers -40°C to 125°C.
PSRR profile and noise rejection
PSRR is specified at 70 dB at 100 Hz, rolling to 45 dB at 1 MHz. That 70 dB at line frequency gives solid rejection of rectified ripple from an AC-DC front end.
Protection set for field robustness
The part integrates over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO). Reverse polarity protection is uncommon in small LDOs and matters for battery-powered designs where the user might insert the cell backwards. UVLO keeps the output off until the input is high enough to maintain regulation — no glitches on power-up.
Active production — no LTB pressure
The TPS71713DCKT is listed as Active and ROHS3 compliant. There is no end-of-life notice on this part.
