D2576-ADJ

Silicore · AC-DC Controllers & Regulators · TO-263-5

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).
