CBM1764DT-1.8-REEL from Corebai Microelectronics, in a TO-263-5. 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 | SHDN | input | Active-low shutdown/enable control. Pulling SHDN low (<0.25V) places the regulator in low-power shutdown; drive high (>2V, up to 5V logic or OC gate with pull-up) to enable. Pin current is typically ~12uA at VSHDN=20V, so an OC driver must supply >20uA. Tie to IN if unused; leaving floating enters micro-power shutdown. |
| 2 | IN | power_in | Power input, 2.7V to 20V operating range. Provides supply to the regulator. Bypass with 1uF-10uF ceramic/tantalum capacitor when the input trace is >6 inches from the bulk supply cap. Tolerates reverse input voltage down to -20V (reverse leakage <1mA) without damage. |
| 3 | GND | power_in | Device ground. The TO-263-5 exposed tab is internally connected to pin 3 (GND) and should be soldered to a copper pour for thermal dissipation (theta-JA ~23°C/W). |
| 4 | OUT | power_out | Regulated 1.8V output, up to 3A load. Requires a minimum 10uF output capacitor (max ESR 3Ω) for stability; larger COUT reduces load-transient peak deviation. Fixed 1.8V (±1.5% typical, tolerances 1.737V to 1.854V over full temperature and load). |
| 5 | SENSE | input | Output sense (feedback) input for fixed-output versions. Connects directly to the internal error amplifier's inverting input. Typically tied to OUT at the load (Kelvin-sense) to compensate PCB trace IR drop; sense current is ~400uA. On the -ADJ variant this pin becomes ADJ (1.2V reference, ~3uA bias), but on CBM1764DT-1.8 it is SENSE. |
