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. |
