TPS73218DCQR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-6

TPS73218DCQR from Texas Instruments, in a SOT-223-6. 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 power_in Input power supply; operating voltage range 1.7 V to 5.5 V
2 OUT power_out Regulated output voltage providing stable regulation without external output capacitor
3 GND power_in Ground connection
4 NR passive Noise reduction pin for connecting external capacitor to bypass bandgap-generated noise and reduce output noise to very low levels; applicable only to fixed voltage versions
5 EN input Enable input; logic high (≥ 1.7 V) enables regulator operation, logic low (≤ 0.5 V) disables regulator with quiescent current ≤ 1 μA
6 GND power_in Ground connection and exposed pad for thermal dissipation
