150 mA fixed-output LDO for noise-sensitive rails
The TPS717285DCKT is a single-output positive LDO from Texas Instruments, delivering 150 mA at a fixed 2.85 V. Its PSRR profile — 70 dB at 100 Hz tapering to 45 dB at 1 MHz — means it rejects switching-regulator ripple across the common 100 kHz to 1 MHz band, making it a candidate for post-regulation of a noisy rail feeding analog or RF stages. Quiescent current sits at 80 µA, low enough for always-on battery-powered rails where every microamp counts.
Protection set and temperature range
On-chip protection includes overcurrent, overtemperature, reverse polarity, and under-voltage lockout (UVLO) — the UVLO prevents the output from turning on until the input is high enough to keep the pass element in regulation, which avoids brown-out glitches on the downstream load. Operating temperature spans -40°C to 125°C, covering automotive under-hood and industrial enclosure ambient conditions.
RoHS3 compliance is confirmed.
