It integrates two LDOs in a single 10-VSON (3x3 mm) package — a space-saving choice for splitting a clean analog rail from a digital rail on the same board. The PSRR spec — 59 dB typical at 120 Hz, rolling to 54 dB — tells you this part filters 120 Hz ripple (full-wave rectified mains) by a factor of roughly 900:1. For a precision ADC or op-amp supply, that keeps line-frequency noise out of the signal chain without a post-filter inductor. ## Protection suite and quiescent current for battery-operated gear Three on-chip protectors — over-temperature shutdown, reverse-polarity blocking, and under-voltage lockout (UVLO) — mean the regulator survives a miswired battery pack or a hot day in an enclosure without latching up or blowing the pass element. Quiescent current is 250 µA typical, with supply current maxing at 600 µA. For a sensor node that spends most of its time in a low-power state, that overhead sits below the self-discharge rate of a 100 mAh coin cell. The adjustable output version can be set from 1.2 V up to 5.5 V, while the fixed option is 1.8 V. The Enable and Power Good control features allow sequencing — Power Good asserts when the output reaches regulation, which can gate the next rail's enable pin. ## Active lifecycle, ROHS3, and industrial temp range Operating temperature spans -40°C to 125°C, covering industrial enclosures and under-hood automotive ambient.","metaTitle":"TPS71319DRCT TI Dual LDO, 250mA, 5.5V, 10-VSON","metaDescription":"Texas Instruments TPS71319DRCT dual 250mA LDO, 5.5V max input, PSRR 59dB~54dB at 120Hz.
