LP5907MFX-3.1

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

LP5907MFX-3.1 from Texas Instruments, in a SOT-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 IN input Input voltage supply; connect a 1µF capacitor at this input.
2 GND power_in Common ground.
3 EN input Enable input; low voltage (< VIL) turns the regulator off and discharges the output pin to GND through an internal 230Ω pulldown resistor; high voltage (> VIH) enables the regulator output; 1MΩ internal pulldown resistor holds the regulator off by default.
4 N/C unconnected No internal electrical connection.
5 OUT output Regulated output voltage; connect a minimum 1µF low-ESR capacitor to this pin; internal 230Ω typical pulldown resistor prevents charge remaining on output when regulator is in shutdown mode (VEN low).
