Product details

Dropout and PSRR — what they mean for your rail

Maximum dropout is 0.18 V at the full 50 mA load. A 63 dB PSRR at 1 kHz attenuates supply ripple. Quiescent current is 115 µA, and the maximum supply current hits 1.2 mA.

Protection and control

Built-in protection covers over-current, over-temperature, reverse polarity, and transient voltage — reducing the need for external clamp diodes or supervisory ICs. An Enable pin allows the regulator to be shut down for power savings or sequenced start-up.

Sourcing and lifecycle

The TPS76038DBVT carries an active product status and is ROHS3 compliant. No last-time-buy or end-of-life notices are in effect. For current pricing and availability, submit an RFQ — availability and price are confirmed at quote time through independent distribution.

Frequently asked questions

What is TPS76038DBVT's PSRR at 1 kHz?

The power-supply rejection ratio is 63 dB at 1 kHz, which provides meaningful attenuation of switching-regulator ripple for analog and RF supply rails.

What package does TPS76038DBVT come in?

It is supplied in a 5-pin SOT-23-5 (SC-74A) surface-mount package, available in Tape & Reel or Cut Tape options.

What compliance documentation does TI provide for TPS76038DBVT?

The part is ROHS3 compliant. Additional compliance documentation (REACH, material declarations) is typically available from Texas Instruments upon request.
