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.
