Inbisen · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT23-5

IBSP3032F033ST5BR00 from Inbisen, in a SOT23-5. 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 power_in Regulator input supply, 2.7 V to 20 V. Bypass to GND with a 2.2 uF or larger ceramic capacitor placed close to the pin.
2 GND power_in Device ground reference and current return.
3 EN input Precision enable input. Drive high (EN_HIGH >= 1.2 V) to turn on the regulator; drive low (EN_LOW <= 1.1 V) to shut down (I_GND-SD ~1.2 uA). Tie EN to VIN for automatic startup.
4 NC unconnected No connect. Leave floating or tie to GND. On the fixed-voltage (F033) SOT23-5 variant this pin replaces the ADJ pin of the adjustable version.
5 OUT power_out Regulated 3.3 V output, up to 300 mA. Requires a 2.2 uF or larger ceramic bypass capacitor (X5R/X7R) to GND for stability. Internal current limit ~480 mA typical.
