CBM1764DT-2.5-REEL from Corebai Microelectronics, in a TO-263-5. 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 | SHDN | input | Active-low shutdown enable that powers the regulator down to micropower shutdown when pulled low, with a typical pin current of about 12uA that requires at least 20uA drive from an open-collector driver with pull-up. |
| 2 | IN | power_in | Supply input for the regulator with a stated input range of 2.7V to 20V, which needs a 1uF to 10uF bypass capacitor when located more than 6 inches from the bulk filter capacitor. |
| 3 | GND | power_in | Ground pin, which is also electrically connected to the TO-263 bottom tab heat-sink pad. |
| 4 | OUT | power_out | Regulated output that requires a minimum 10uF output capacitor to prevent oscillation, with larger capacitance reducing load-transient peak voltage. |
| 5 | SENSE | input | Output sense input for the fixed-voltage version that connects to the internal error amplifier inverting input, where tying it to OUT at the load gives the best regulation accuracy. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
