NCV5500DADJR2G
onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8
NCV5500DADJR2G from onsemi, in a SOIC-8. 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 | Vin | power_in | Positive power supply input; operating input is Vout + VDO (minimum 2.5 V) up to 16 V, and the absolute maximum input voltage is 18 V. |
| 2 | GND | power_in | Ground, internally connected to the Tab heat sink on the other packages. |
| 3 | GND | power_in | Ground, internally connected to the Tab heat sink on the other packages. |
| 4 | Vout | power_out | Regulated output voltage; the adjustable version is set to 1.25 V to 5.0 V and delivers up to 500 mA. |
| 5 | NC/ADJ | input | On the adjustable version this is the voltage-adjust input, where an external divider sets the output over 1.25 V to 5.0 V (no connection on fixed-output versions). |
| 6 | GND | power_in | Ground, internally connected to the Tab heat sink on the other packages. |
| 7 | GND | power_in | Ground, internally connected to the Tab heat sink on the other packages. |
| 8 | EN | input | Enable pin: a level above 2.0 V turns the output on and below 0.4 V turns it off to a minimal-current shutdown; connect to Vin if unused. |
