Package and mounting
The Texas Instruments LP5912-2.5DRVT is a single-output positive LDO that delivers a fixed 2.5 V at up to 500 mA. It is built for noise-sensitive analog and digital rails where a clean, regulated supply is critical — think ADC front-ends, sensor bias, or MCU core power in industrial or automotive environments. The PSRR holds 80 dB at 100 Hz and rolls to 40 dB at 100 kHz, which means it knocks down power-supply ripple across the audio band and into the switching-regulator range. Quiescent current sits at 55 µA, so it does not kill battery life in always-on subsystems.
Package and mounting
Enable, Power Good, and Soft Start are on-chip. Soft Start limits inrush on the output cap — useful if the load side has a large decoupling bank. The 6-WSON with exposed pad is hand-reworkable with hot air and a fine tip; the 2x2 mm body is small but the pad is centred, so alignment is straightforward. The part ships in Tape & Reel or Cut Tape, so prototyping quantities are easy to order alongside production reels.
