Input voltage maxes at 10 V, and the output adjusts from 1.25 V up to 9.3 V via an external resistor divider. The 55 dB PSRR at 120 Hz gives it decent line-frequency rejection for post-regulating a switching pre-regulator or powering sensitive analog loads like op-amp rails or ADC reference buffers. Operating temperature spans -40°C to 125°C, so it handles under-hood automotive and factory-floor enclosures without a derating curve. The 6-WSON exposed-pad package (2.92 x 3.29 mm) keeps the footprint small, but the pad needs a good thermal via pour to shed the 1 A heat. ## 55 dB PSRR — what it buys you At 120 Hz the LP8340ILDX-ADJ/NOPB delivers 55 dB of ripple rejection. ## Quiescent current and protection Quiescent current sits at 100 µA typical, with a maximum supply current of 170 µA. That's not ultra-low-power territory (the TPS7A0313 draws 300 nA Iq), but it's low enough for always-on automotive modules that need to stay under a few mA standby budget. Protection includes over-current and over-temperature shutdown — no reverse-current or UVLO, so watch the input sequencing if the output bus holds up a large capacitor. The single regulator topology means one enable pin, no power-good flag. ## Active and available through distribution The LP8340ILDX-ADJ/NOPB carries an active lifecycle status — no last-time-buy notice, no end-of-life risk for current designs.","metaTitle":"LP8340ILDX-ADJ/NOPB LDO Regulator, 1A Adjustable, 6-WSON","metaDescription":"Texas Instruments LP8340ILDX-ADJ/NOPB positive adjustable LDO, 1A output, 55dB PSRR at 120Hz, -40 to 125°C, 6-WSON.
