The 62 µA quiescent current keeps the draw low enough for always-on modules that stay powered with ignition off — a body controller or telematics unit that sits on the battery bus. ## PSRR profile and noise rejection PSRR is 68 dB at 100 Hz, dropping to 28 dB at 100 kHz. The 40 dB roll-off means switching noise from a DC-DC converter above 100 kHz passes through with only about 28 dB of rejection — a 100 mVpp ripple on the input becomes roughly 4 mVpp on the output. If the downstream load is an analog sensor or ADC reference, an additional LC filter ahead of the LDO is worth the board area. ## Package and thermal design Surface-mount only; the exposed pad carries the ground return and the thermal path. A via array under the pad to an inner-layer ground plane drops the junction-to-board thermal resistance significantly. ## Protection and control Built-in protection includes current limit, thermal shutdown, and undervoltage lockout (UVLO). The enable pin allows the regulator to be gated by a GPIO or a power-sequence controller — the output stays off until the enable pin is pulled high. ROHS3 compliant with no exemptions — no conflict with EU or automotive substance restrictions.","metaTitle":"Texas Instruments TLV73312PQDRVRQ1 LDO, 300mA, 1.2V Fixed","metaDescription":"Texas Instruments TLV73312PQDRVRQ1 automotive LDO, 300mA output, fixed 1.2V, AEC-Q100 Grade 1, 6-WSON.
