It is qualified to AEC-Q100 and rated for a junction temperature range of -40°C to 150°C, which covers under-hood and transmission environments. The 70 dB PSRR at 1 kHz keeps noise from the 40 V bus out of sensitive analog and digital loads, while the 26 µA quiescent current suits always-on modules in battery-backed systems. ## Protection and control Built-in protection includes over-current, over-temperature, and under-voltage lockout (UVLO). An Enable pin allows the regulator to be gated by a system supervisor or ignition signal. The fixed 3.3 V output eliminates the need for an external resistor divider. ## Package and mounting Supplied in a TO-252-5 (DPak) surface-mount package with four leads plus a tab. The tab is the main thermal path; PCB copper area under the tab determines the effective thermal resistance at the 150°C junction limit. ## Lifecycle and sourcing The TPS7B8633QKVURQ1R2 is listed as Active with no last-time-buy or end-of-life notice. It is an automotive-grade part released for production use.","metaTitle":"TI TPS7B8633QKVURQ1R2 LDO Regulator, 500 mA, 40 V, AEC-Q100","metaDescription":"TI TPS7B8633QKVURQ1R2 automotive LDO: 3.3 V fixed output, 500 mA, 40 V input, PSRR 70 dB at 1 kHz, 26 µA Iq, TO-252-5.
