RT9183HPS from Richtek Tech, in a SOP-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 | EN | input | Chip enable control input (RT9183H: active high, logic-high ≥1.2V on, logic-low ≤0.6V off); the device is unstable if this pin is left unconnected. |
| 2 | VIN | power_in | Supply input operating from 2.3V to 5.5V (7V absolute maximum), requiring about 10µF to ground placed within 1cm of the pin. |
| 3 | VOUT | power_out | Regulator output delivering up to 1.5A, with 10µF to 47µF output capacitor to ground for stability. |
| 4 | ADJ | input | Output voltage is set by internal feedback resistors when grounded, or by external resistors per VOUT = 0.8×(1+R1/R2) V with R2 below 80k. |
| 5 | GND | power_in | Common ground. |
| 6 | GND | power_in | Common ground. |
| 7 | GND | power_in | Common ground. |
| 8 | GND | power_in | Common ground. |
