IDCHIP · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89
7350-1 from IDCHIP, in a SOT-89. 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 | GND | power_in | Ground pin (地), the common return for the regulator. |
| 2 | VIN | power_in | Supply input pin; absolute maximum input voltage is 0 to +45 V (Note 1), and the recommended input range is +2.5 to +45 V. |
| 3 | VOUT | power_out | Regulated output pin; it must have a capacitor greater than 1 uF to ground, and the 7350-1 output voltage is 5.0 V. |
