TPS72730DSER

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · WSON-6(1.5x1.5)

TPS72730DSER from Texas Instruments, in a WSON-6(1.5x1.5). 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 OUT output Regulated output voltage pin; a small 1-μF ceramic capacitor is needed from this pin to ground to assure stability.
2 NC unconnected No connection; this pin can be tied to ground to improve thermal dissipation.
3 GND power_in Ground pin.
4 EN input Driving EN over 0.9 V turns on the regulator, and driving EN below 0.4 V puts the regulator into shutdown mode, reducing operating current to 120 nA nominal.
5 NC unconnected No connection; this pin can be tied to ground to improve thermal dissipation.
6 IN input Input pin; a small capacitor is needed from this pin to ground to assure stability.
