Shanghai Siproin Microelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3
H7245-1 from Shanghai Siproin Microelectronics, 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 | Ground (VSS) reference pin for the regulator. |
| 2 | VIN | power_in | Supply input, operating range 3.5V to 15V with an absolute maximum of 18V; a 1uF input capacitor is used in the typical application. |
| 3 | VOUT | power_out | Regulated 4.5V output (H7245-1, ±2% tolerance) delivering up to 400mA at Vin-Vout=1V, with a 1uF tantalum or 6.8uF ceramic output capacitor recommended. |
