ST730M50R

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

ST730M50R from STMicroelectronics, in a SOT-23-5L. 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 VOUT power_out Regulated output voltage pin, which for the 5.0 V fixed version ST730M50R delivers 5.0 V with up to 300 mA.
2 GND power_in Ground reference pin to which all datasheet absolute maximum ratings are referred.
3 VIN power_in Input voltage pin that supplies the regulator and must be decoupled with an input capacitor placed close to it.
4 NC/ADJ unconnected Not internally connected in the fixed version, so it is left unconnected on the ST730M50R, whereas the adjustable version uses it to connect an external resistor divider that sets the output voltage.
5 EN input Enable pin where low puts the device in shutdown and high activates it, and it must not be left floating.
