RT9058-90GVL

Richtek Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3L

RT9058-90GVL from Richtek Tech, in a SOT-23-3L. 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 reference pin for the regulator; place the input and output capacitors close to the GND pin.
2 VOUT power_out Regulated 9.0V output; for this variant VOUT to GND is rated up to 15V and VOUT to VCC down to -40V, and the output capacitor must be at least 1µF effective with at least 1mΩ ESR.
3 VCC power_in Supply voltage input with a recommended range of 3.5V to 36V and an absolute maximum of 40V to GND; use a 1µF or larger input capacitor placed close to VCC and GND.
