XC6702D331PR-G

Torex Semicon · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-5

XC6702D331PR-G from Torex Semicon, in a SOT-89-5. 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 VOUT power_out Regulator output, fixed at 3.3 V for this part (XC6702D331, 1.8 V to 18.0 V range, ±1% accuracy); output current is rated to 300 mA and the absolute maximum VOUT is -0.3 V to VIN + 0.3 V or 42.0 V, whichever is lower.
2 VSS power_in Ground reference pin; all voltage ratings in the datasheet are relative to VSS.
3 CE input ON/OFF control, active high: H enables the regulator, L puts it in standby (supply current 0.1 µA), and the pin must not be left open, so it should be held at a fixed voltage; absolute maximum VCE is -0.3 V to 42.0 V.
4 NC unconnected No connection on the SOT-89-5 package.
5 VIN power_in Power input, operating range 4.5 V to 36.0 V with absolute maximum rating 42.0 V (surge 46.0 V for transients up to 400 ms).
