RT9193-25GB

Richtek Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

RT9193-25GB from Richtek Tech, in a SOT-23-5. 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 VIN power_in Power input voltage, recommended operating range 2.5V to 5.5V (absolute maximum 6V), with the input capacitor placed within 0.5 inch of the pin.
2 GND power_in Ground.
3 EN input Chip enable, active high (above 1.2V on, below 0.4V shutdown); the pin is high impedance, so use a 100kΩ pull-down to GND if the control signal floats, or tie to VIN if unused.
4 BP passive Reference noise bypass; may be left floating, but for lowest noise connect a 22nF capacitor between BP and GND.
5 VOUT power_out Regulated output voltage (2.5V for the -25 option), up to 300mA, requiring at least a 1µF output capacitor for stability.
