What sets it apart from a garden-variety LDO is the 30V maximum input — that is a wide input tolerance that lets it drop straight off a 24V industrial rail or an unregulated 12V battery line without a pre-regulator. The 2.05 µA quiescent current means it idles on a battery-powered sensor node without draining the cell, and the -40°C to 125°C operating range covers engine-bay and outdoor enclosure temperatures. It comes in a SOT-23-5 package, which is a standard footprint you will find on any rework station. ## 30V input, 1.2V out — the gap it fills The PSRR profile — 80 dB at 10 Hz rolling off to 52 dB at 1 kHz — tells you it attenuates low-frequency ripple well but starts to let higher-frequency noise through. That is fine for powering a microcontroller or a low-speed ADC reference; for a high-resolution audio codec or a precision analog front-end running above 1 kHz, you would want a post-filter or a different LDO with higher bandwidth rejection. ## Protection set — saves external parts The TPS70912DBVT packs over-current, over-temperature, reverse-current, and under-voltage lockout protection into the SOT-23-5 package. The reverse-current block is the one that saves a diode on the output — if the output voltage ever exceeds the input (back-feed from a battery or a second supply), the regulator blocks reverse current flow. That is one less Schottky on the BOM. UVLO keeps the output off until the input rail is high enough for clean regulation, which avoids brownout glitches on power-up. ## Sourcing and lifecycle No end-of-life notice, no last-time-buy window to track. The SOT-23-5 package is a common footprint, so board layout is straightforward and the part is easy to hand-solder or reflow on a standard profile.","metaTitle":"TI TPS70912DBVT LDO Regulator, 1.2V Fixed, 150mA, SOT-23-5","metaDescription":"Texas Instruments TPS70912DBVT linear regulator: 1.2V fixed output, 150mA, 30V input max, 2.05 µA quiescent current, SOT-23-5.

If the output voltage rises above the input, the regulator blocks reverse current flow — no external Schottky diode needed on the output."},{"question":"What is the quiescent current of TPS70912DBVT?","answer":"The quiescent current is 2.05 µA typical. That is the current the regulator draws from the input when the output is loaded — it stays low across the temperature range, making it suitable for battery-powered always-on applications."},{"question":"What is a direct replacement for TPS70912DBVT?","answer":"Within the TPS709 family, the fixed-output variants differ only by output voltage. The TPS70912DBVT is the 1.2V version.
