This voltage is typical for low-voltage core rails in automotive microcontrollers, FPGAs, or sensor ASICs that require a tightly regulated 0.9 V supply from a higher input bus up to 6.5 V. The 55 µA quiescent current keeps the regulator's own draw low in always-on or sleep-mode circuits, while the 600 µA maximum supply current bounds the total overhead at full load. ## PSRR profile and noise rejection Power-supply rejection ratio is specified at 65 dB at 100 Hz, rolling off to 40 dB at 100 kHz. This means the LDO attenuates low-frequency ripple from the upstream rail by a factor of roughly 1800 at 100 Hz, but the rejection drops to about 100× at 100 kHz — switching noise from a DC-DC converter above that crossover will pass through unless filtered ahead of the LDO. ## Automotive qualification and protection suite The protection block includes over-temperature shutdown, reverse-polarity immunity, and short-circuit current limiting — three failure modes common in automotive power distribution. The exposed pad carries the ground potential and provides the primary heat path into the board. Control features include an enable pin, a power-good output for sequencing, and a soft-start ramp to limit inrush current on the output capacitor.","metaTitle":"LP5912Q0.9DRVTQ1 LDO, 0.9V fixed, 500mA, AEC-Q100","metaDescription":"Texas Instruments LP5912Q0.9DRVTQ1 LDO, fixed 0.9V output, 500mA, AEC-Q100 automotive grade.
