CBM1764DT-1.5-REEL

Corebai Microelectronics · Linear Voltage Regulators (LDO) · TO-263-5

CBM1764DT-1.5-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 control; when low the output is turned off, typical pin current about 12uA, must be tied to the supply if unused (floating enters micropower shutdown).
2 IN power_in Power input, operating range 2.7V to 20V with reverse-input protection to -20V, with a 1uF to 10uF bypass capacitor recommended if far from the supply filter capacitor.
3 GND power_in Ground; the TO-263-5 bottom tab is connected to this pin.
4 OUT power_out Regulated output delivering up to 3A, requiring a minimum 10uF output capacitor for stability.
5 SENSE input Output feedback sense pin on fixed-output versions (this 1.5V part), connected to the error amplifier inverting input and tied to OUT (or load for Kelvin sensing), with about 400uA current.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
