Product details

Fixed 1.85V rail, 500mA capacity — what the ratings mean for the BOM

The Texas Instruments TLV755185PDQNR is a single-output, positive-voltage LDO regulator delivering a fixed 1.85V output at up to 500mA. It is designed for space-constrained, noise-sensitive applications such as RF transceivers, sensor front-ends, and MCU core supplies where a clean, regulated rail is required.

Protection features and operating range

Built-in over-current, over-temperature, and under-voltage lockout (UVLO) protection cover the common fault conditions. UVLO prevents the output from turning on until the input voltage is high enough to regulate, avoiding brown-out operation. The -40°C to 125°C junction temperature range covers automotive under-hood and industrial enclosure environments without derating at the low end.

Frequently asked questions

Is TLV755185PDQNR compatible with 3.3V input?

Yes. The maximum input voltage is 5.5V, so a 3.3V rail is well within range. With 0.4V dropout at 500mA, the headroom is over 1V — sufficient for clean regulation.

What is TLV755185PDQNR's PSRR rating?

PSRR is 52dB across the 1kHz to 1MHz frequency range. This wide-band specification means the regulator attenuates ripple from switching converters effectively into the MHz region.
