The 85 dB PSRR at 1 kHz means that ripple from an upstream switching regulator — say a buck converter switching at 1 kHz — is attenuated by a factor of roughly 18,000 before it reaches the analog load. ## Protection set that covers the common field faults Over-current and over-temperature shut-down are standard on most LDOs, but the reverse-polarity protection is the differentiator here — it clamps a miswired battery or reversed input without needing an external Schottky diode in series. In an automotive or industrial 24 V panel where the field-wiring polarity is not always verified, this saves a board spin. The -40°C to 125°C operating range covers the full automotive temperature band — under-hood ECUs that see 105°C ambient and 125°C junction have margin. The SOT-23-5 footprint fits a standard 2.9 mm × 1.6 mm land pattern; the thermal pad on the PCB is the only heatsink, so the 100 mA output at 125°C ambient requires the copper area recommended in the datasheet's thermal table.","metaTitle":"TPS78925DBVT LDO 2.5V 100mA SOT-23-5, 85dB PSRR","metaDescription":"Texas Instruments TPS78925DBVT fixed-output LDO, 2.5V at 100mA, 85dB PSRR at 1kHz, -40 to +125°C.

This means that a 100 mV peak-to-peak ripple on the input at 1 kHz appears as roughly 5.6 µV at the output — the attenuation is strong enough to keep the rail clean for a precision analog front-end or a 16-bit ADC reference without a post-filter."},{"question":"What package does TPS78925DBVT come in?","answer":"The TPS78925DBVT is supplied in the SC-74A, SOT-753 package, also referred to as SOT-23-5. The 5-pin footprint is shared across the TPS789 family, so a voltage variant swap does not require a PCB change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS78925DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS78925DBVT when reusing this data.
