LP5907QMFX-1.2Q1

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

LP5907QMFX-1.2Q1 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 power_in Input voltage supply; connect a 1-µF capacitor at this input.
2 GND power_in Common ground.
3 EN input Enable input: a low voltage (< VIL) turns the regulator off and discharges the output to GND through an internal 230-Ω pulldown, a high voltage (> VIH) enables the regulator output, and an internal 1-MΩ pulldown holds the regulator off by default.
4 N/C unconnected No internal electrical connection.
5 OUT power_out Regulated output voltage; connect a minimum 1-µF low-ESR capacitor to this pin, and an internal 230-Ω (typical) pulldown prevents charge remaining on VOUT in shutdown.
