D2576-ADJ from Silicore, 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 | VIN | power_in | Positive input supply voltage requiring minimum 100 µF bypass capacitor located near the regulator for stability and switching current delivery. |
| 2 | OUTPUT | output | Internal switch output with voltage switching between (+VIN - VSAT) and approximately -0.5V; minimize PCB copper area connected to this pin to reduce electromagnetic coupling. |
| 3 | GND | power_in | Circuit ground reference. |
| 4 | FEEDBACK | input | Voltage feedback sensing input to regulate output voltage; for fixed versions wired to output, for adjustable version uses external resistor divider network with bias current Ib = 50-100 nA. |
| 5 | ON/OFF | input | Logic-level shutdown control input accepting TTL/CMOS signals (VIL=0.8V, VIH=2.0V) to toggle between normal operation and standby mode at 50-200 µA quiescent current. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
