That means the input rail must stay at least 150 mV above the programmed output voltage across the load range — a 3.3 V output needs at least 3.45 V at the input pin, not just the nominal 3.3 V. The input max is 5.5 V, so a 5 V rail with 10 % tolerance (4.5–5.5 V) gives plenty of headroom. Output is adjustable from 1.2 V up to 5.5 V using an external resistor divider. The fixed 1.2 V version is also available under the same order code — the datasheet's adjustable/fixed designation means the device can be configured either way depending on the feedback pin connection. ## PSRR profile — 58 dB at 100 Hz, 37 dB at 10 kHz Power supply rejection ratio is 58 dB at 100 Hz, rolling off to 37 dB at 10 kHz. This covers the dominant noise bands from a 50/60 Hz mains ripple and the switching fundamental of a typical DC-DC converter upstream. ## Quiescent current and protection suite That is moderate for an automotive LDO — not the ultra-low-Iq class, but acceptable for always-on modules where the load current is in the tens of milliamps. The protection block includes over-current, over-temperature, short-circuit, and reverse polarity — the reverse polarity clamp is a differentiator versus some peers that omit it. ## 8-SON exposed-pad package — thermal and footprint Reflow profile follows standard lead-free solder (260°C peak). No moisture sensitivity level is stated in the record, but an 8-SON with exposed pad typically requires MSL 1 or 2; confirm with the lot date code if the parts have been in storage.","metaTitle":"TI TPS73201QDRBRQ1 LDO Regulator, 250 mA, 8-SON","metaDescription":"Texas Instruments TPS73201QDRBRQ1 LDO, 250 mA output, 150 mV dropout, PSRR 58–37 dB, AEC-Q100, active production.
