Active production — what that means for your BOM
The TPS71726DCKT is listed as Active — Texas Instruments continues to manufacture it, so new designs can commit to this part without an imminent last-time-buy clock. ROHS3 compliant, no lead or restricted substance concerns for EU-market boards.
150 mA LDO — the PSRR is the headline
This is a single-output positive LDO, fixed at 2.6 V, delivering up to 150 mA. The PSRR spec — 70 dB at 100 Hz, rolling to 45 dB at 1 MHz — tells you where this regulator earns its keep: it cleans up low-frequency ripple from a switching pre-regulator or a noisy rail feeding an analog front-end. At 1 MHz the 45 dB still gives roughly 180:1 rejection, enough to keep a 10 mV switching ripple below 60 µV at the output. Dropout is 0.3 V max at full load — the input rail needs to stay above 2.9 V to hold regulation. Quiescent current is 80 µA typical, max 100 µA, so the regulator's own draw won't eat into the 150 mA budget in a battery-powered design.
Protection set and temperature range
Over-current, over-temperature, reverse polarity, and under-voltage lockout are all on-chip — no external supervisor needed for basic fault handling. The Enable pin lets a processor or a power sequencer gate the output — useful for sequencing multiple rails on power-up.
