RT9183HPS

Richtek Tech · Linear Voltage Regulators (LDO) · SOP-8

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.
