TPS73633DBVT

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

TPS73633DBVT from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN input Input supply pin; the recommended input voltage is 1.7 V to 5.5 V and the absolute maximum on VIN is -0.3 V to 6 V.
2 GND power_in Ground pin, which must be connected to the ground plane; bypass capacitor ground connections must go directly to this pin.
3 EN input Active-high enable: driving above 1.7 V (min) turns the regulator on, and driving below 0.5 V (max) puts it in shutdown; absolute maximum on VEN is -0.3 V to 6 V.
4 NR passive Noise-reduction pin on fixed-voltage versions only; an external capacitor connected from NR to ground bypasses the internal bandgap noise and lowers output noise.
5 OUT output Regulator output, rated for 0 mA to 400 mA load current, and stable without an external output capacitor.
