Product details

The Texas Instruments TLV1117-25CDCY is a single-output, fixed 2.5 V positive LDO regulator rated for 800 mA continuous output.

Protection and quiescent draw

Built-in over-current and over-temperature protection let the part survive momentary shorts or thermal excursions without external clamp diodes. Quiescent current is 10 mA — not a micropower LDO, but acceptable for always-on rails in mains-powered equipment where the 10 mA Iq is a small fraction of the load budget.

No last-time-buy window is open, and no successor has been announced.

Frequently asked questions

What is the PSRR of TLV1117-25CDCY?

The listed PSRR is 75 dB at 120 Hz. This is the ripple-rejection figure for the dominant power-line frequency after rectification.
