Richtek Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
RT9167A-18GB 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; the datasheet gives an input voltage range of 2.9V to 7V (2.7V to 7V at IL = 50mA) and an absolute maximum input of 8V. |
| 2 | GND | power_in | Ground; connect to a large pad or ground plane, since the GND pin also carries heat away from the device. |
| 3 | EN | input | Chip enable, active high: VIH minimum is 1.6V and VIL maximum is 0.4V (VIN = 3V to 5.5V), and the pin must not be left floating, so tie it to VIN if shutdown is not used. |
| 4 | BP | passive | Reference noise bypass; a 10nF capacitor with the internal 200kΩ resistor forms an 80Hz low-pass filter, and the capacitor must have very low leakage. |
| 5 | VOUT | power_out | Regulated output, selectable from 1.5V to 5V in 100mV steps with 2% accuracy; stable with at least 1µF ceramic output capacitor and ESR greater than 5mΩ. |
