TPS7A2025PDQNR

TPS7A2025PDQNR is the 2.5 V fixed-output code of TI's TPS7A20 low-noise LDO family: 300 mA from a 1.6 V to 6.0 V input in a 1.0 x 1.0 mm X2SON-4 package, aimed at space-starved rails for sensors, wearables and RF front ends. The headline figures are 7 µVRMS output noise with no noise-bypass capacitor required, 95 dB PSRR at 1 kHz, a typical quiescent current of 6.5 µA and ±1.5% accuracy held across line, load and temperature; dropout is 140 mV max at the full 300 mA. A smart enable pulldown leaves the output safely off when EN floats, soft-start limits inrush, and the part is stable with a 1 µF ceramic output capacitor. TI's package addendum lists this code Active in production, on a 3,000-piece reel with marking JG. Selection advice: the 25 is the 2.5 V output — the family spans many voltages in this footprint, so quote the complete code. Parameters verified against TI documentation.
