Its 55 µA quiescent current keeps battery drain low in always-on sensor nodes or wireless modules, while the PSRR of 65 dB at 100 Hz dropping to 40 dB at 100 kHz cleans up ripple from switching pre-regulators feeding analog or RF front-ends. ## Thermal and protection envelope Junction temperature rating of -40°C to 125°C covers industrial enclosures and under-hood automotive zones. The 6-WSON (2x2 mm) exposed pad pulls heat into the PCB copper plane — layout the pad to a thermal via array if running near 500 mA at high ambient. On-chip protection includes over-temperature shutdown, reverse polarity blocking, and short-circuit current limiting, which saves external clamp diodes in field-wired or battery-powered gear. ## Control features and BOM simplicity Enable pin allows sequenced power-up; Power Good output signals the downstream load when the output is within regulation. Soft start limits inrush current on the 0.9 V rail, useful when powering an MCU core or FPGA bank that presents a large capacitive load at turn-on. Fixed output eliminates the feedback resistor divider, saving two components and one tolerance stack-up.","metaTitle":"LP5912-0.9DRVT LDO Regulator, 0.9V Fixed, 500mA, 6-WSON","metaDescription":"LP5912-0.9DRVT from TI: fixed 0.9V LDO, 500mA output, 55µA Iq, PSRR 65dB at 100Hz.
