BD450M5WFPJ-CZE2
ROHM Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-5
BD450M5WFPJ-CZE2 from ROHM Semicon, in a TO-252-5. 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 | VCC | power_in | Supply voltage input pin; the datasheet gives a wide operating input range of 3.0 V to 42 V and a 45 V absolute maximum voltage. |
| 2 | CTL | input | Output control (enable) pin; a logical HIGH enables the device and a LOW disables it. |
| 3 | GND | power_in | Ground pin. |
| 4 | N.C. | unconnected | Not connected; the datasheet recommends shorting it to GND, but it can be left open because it is not connected inside the IC. |
| 5 | VOUT | power_out | Regulated output pin (3.3 V or 5.0 V, 500 mA output current capability). |
| 6 | FIN | power_in | Fin (heat-sink tab) connected to GND, printed as pin 6 in the pin description table. |
