TPS72301DDCR from Texas Instruments, in a TSOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Device ground / network ground reference. All voltages in the datasheet are referenced to this terminal.
2 IN power_in Negative input supply. Operating range -10 V to -2.7 V (absolute max -11 V to +0.3 V). Requires a 2.2 uF ceramic input capacitor to GND for stability.
3 EN input Bipolar enable input. Driving above VEN(HI) = +1.5 V or below VEN(LO) = -1.5 V enables the regulator; driving between VDIS(HI) = +0.4 V and VDIS(LO) = -0.4 V places the device in shutdown. Abs max -VI to +5.5 V.
4 FB input Feedback input to the internal error amplifier (adjustable TPS72301 variant). Set output voltage with an external resistor divider from OUT to FB to GND; VFB = -1.186 V typical (-1.210 V to -1.162 V). Feedback current 0.05 uA typ.
5 OUT power_out Regulated negative output voltage (adjustable -1.2 V to -10 V). Requires a 2.2 uF ceramic capacitor from OUT to GND for stability. Output current 0 to 200 mA; internal current limit 550 mA typ.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (29 pp, sha256 73978a85de4d8f57, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
