XC6504A331MR from TECH PUBLIC, 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 | Supply input voltage pin. Operating range 1.2V to 5.5V (absolute max -0.3 to +6.5V). Should be decoupled to GND with a 1-10µF ceramic or tantalum capacitor placed close to the pin. |
| 2 | GND | power_in | Device ground reference. Typical ground (quiescent) current is 2µA at no load; shutdown ground current is 0.1µA typical (0.5µA max). |
| 3 | CE | input | Chip Enable (active-high). VIH ≥ 1.0V enables the regulator; VIL ≤ 0.4V places the device in shutdown. EN input current is 10nA typ (100nA max) at VEN=5V. When disabled, the output is actively discharged through ~100Ω. |
| 4 | NC | unconnected | No internal connection. May be left floating or tied to GND for mechanical stability. |
| 5 | OUT | power_out | Regulated voltage output, fixed at 3.3V (±2% accuracy) for the '331' option. Sources up to 300mA; dropout ≈0.18V at 300mA with VOUT=3.3V. Requires a 1-10µF ceramic or tantalum output capacitor to GND for stability. |
