BD433M5FP-CE2

ROHM · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252

BD433M5FP-CE2 from ROHM, in a TO-252. 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 VCC power_in Supply voltage input pin. Absolute maximum -0.3 V to +45.0 V; recommended operating range 4.0 V to 42 V (start-up 3.0 V min at IOUT = 0 mA). Bypass to GND with CIN ≥ 0.1 µF located close to the pin.
2 N.C. unconnected Not Connected internally. May be left open, but ROHM recommends shorting to GND on the PCB for best practice.
3 VOUT power_out Regulated 3.3 V (Typ., ±2 %) output pin. Delivers up to 500 mA. Requires COUT ≥ 10 µF (Typ., ≥ 6 µF over temp/DC-bias) between VOUT and GND for stable operation; ceramic (X5R/X7R), tantalum, or electrolytic accepted. Absolute max VOUT range -0.3 V to +8.0 V.
4 GND power_in Ground / exposed thermal tab (FIN) on the back of the TO-252-3 package. Also serves as the primary heat-sinking path - solder to a copper pour for improved θJA. Keep at the lowest system potential under all operating conditions.
