TPS7A3001DGNR

TPS7A3001DGNR is the tape-and-reel HVSSOP-8 (DGN) ordering code for the Texas Instruments TPS7A30 negative-voltage low-dropout regulator, listed as Active / Production in the datasheet package option addendum. It takes a -3 V to -35 V input and regulates an adjustable -1.18 V to -33 V output at up to 200 mA, with 15.1 µVRMS output noise over 10 Hz to 100 kHz, PSRR of 72 dB at 120 Hz and at least 55 dB from 10 Hz to 700 kHz, a dropout voltage of 216 mV typical at 100 mA and a quiescent current of 50 µA typical. The selection point is a clean negative rail for analog front ends: op-amp and data-converter negative supplies in industrial and test equipment where an inverting charge pump plus filtering would cost more board area and noise budget. Selection advice: the output is set by a resistor divider against the internal reference, and stability depends on the output capacitor type and ESR window given in the datasheet, so copy the reference layout before substituting capacitor families. Parameters verified against the TI TPS7A30 datasheet SBVS125 (package option addendum and electrical characteristics).
