2.5 V fixed rail for analog and digital loads
The Texas Instruments TLV1117-25CDCYRG3 is a single-output positive fixed LDO regulator delivering a 2.5 V rail at up to 800 mA. It is built for surface-mount assembly in the SOT-223-4 package (TO-261-4 compatible footprint) and operates over a 0°C to 125°C range. The 75 dB PSRR at 120 Hz makes it a natural fit for cleaning up rectified mains ripple before feeding analog or mixed-signal circuitry — ADC references, sensor front-ends, or low-noise bias rails. Over-current and over-temperature protection are built in, so it can handle a brief overload on the output without failing short.
Dropout and headroom — what 1.3 V max means on the board
The maximum dropout voltage of 1.3 V at the full 800 mA load sets the minimum input-to-output differential the designer must budget.
Active lifecycle — no LTB watch needed
The part carries an active product status with RoHS3 compliance. There is no end-of-life notice, no last-time-buy window to track.
