RT9193-30GB from Richtek Tech, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; 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 max 6V). Bypass with 1µF X7R ceramic to GND close to the pin. |
| 2 | GND | power_in | Device ground reference for the regulator, EN logic and BP bypass network. |
| 3 | EN | input | Chip Enable, active-high TTL-logic input (VIH ≥ 1.2V, VIL ≤ 0.4V, 0-5.5V range). High-impedance pin (IBSD ≤ 100nA); tie through a 100kΩ pull-down to GND if the drive signal can float. Drive to GND for <0.01µA shutdown. |
| 4 | BP | passive | Reference noise bypass. Connect a 22nF ceramic capacitor between BP and GND for lowest output noise (typ 100µVRMS, 10Hz-100kHz). May be left floating if noise performance is not critical. |
| 5 | VOUT | power_out | Regulated output voltage (3.0V for the -30 option). Delivers up to 300mA with 220mV dropout at 300mA. Requires only 1µF X7R ceramic to GND for stability; low-ESR ceramic capacitors are supported. |
