LP3992-12B5F

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

LP3992-12B5F from LOWPOWER, 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 VIN power_in Power input voltage. Operating range 2.5V to 5.5V, absolute maximum 6.5V. Requires a >=1uF bypass capacitor located within 0.5 inch of the pin.
2 GND power_in Device ground reference for the LDO regulator and internal reference.
3 EN input Chip enable, active high. VIH >= 1.4V starts the regulator; VIL <= 0.4V places the device in shutdown (<0.01uA typical). EN input bias current 1.5uA typ at VEN=3V. Tie to VIN for always-on operation.
4 NC unconnected No internal connection. Leave floating or tie to ground for best PCB layout.
5 VOUT power_out Regulated 1.2V output, 300mA rated (current limit 420-450mA). Requires a low-ESR ceramic output capacitor >=1uF for stability, placed within 0.5 inch of the pin.
