For a sensor supply or analog front-end sharing a rail with a switching converter, this keeps the noise floor low enough for 12-bit resolution without additional post-filtering. Quiescent current is 28 µA typical — the regulator's own draw is below the self-discharge rate of a small automotive battery, making it suitable for always-on modules like body controllers or CAN transceivers that must draw microamps when the ignition is off. ## Protection and control features for system reliability On-chip protection covers over-current, over-temperature, and reverse polarity — the latter is critical in automotive harnesses where a miswired battery connection can otherwise damage downstream ICs. An enable pin allows the system MCU to shut down the regulator when the load is idle, cutting the total current draw to near zero in sleep mode.","metaTitle":"TPS76933QDBVRG4Q1 LDO Regulator, 3.3V Fixed, 100mA, AEC-Q100","metaDescription":"Texas Instruments TPS76933QDBVRG4Q1 automotive LDO, 3.3V fixed output at 100mA, 60dB PSRR at 1kHz, -40 to 125°C.
