H7218-1
Shanghai Siproin Microelectronics · Linear Voltage Regulators (LDO) · SOT-89-3
H7218-1 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 pin (Vss), reference for the 1.8V output; pin order left to right in top view is GND, VIN, VOUT. |
| 2 | VIN | power_in | Input supply pin, operating input voltage 3.5V to 15V (absolute maximum 18V), decouple with 1uF input capacitor. |
| 3 | VOUT | power_out | Regulated 1.8V output (±2%) delivering over 400mA, with 1uF tantalum or 6.8uF ceramic output capacitor recommended. |
