HL · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
7550 from HL, in a SOT-89-3. 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 | System ground reference pin for the regulator (absolute maximum ratings are given relative to GND). |
| 2 | Vin | power_in | Input pin; absolute maximum Vin to GND is 30 V, and the datasheet's electrical characteristics specify an input voltage range of 3 V to 24 V at no load. |
| 3 | Vout | power_out | Regulated output pin; absolute maximum Vout to GND is 15 V, and output current is rated up to 150 mA (short-circuit current typically 100 mA). |
