LM7905D2TRG

HANSCHIP semiconductor · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-263-2

LM7905D2TRG from HANSCHIP semiconductor, in a TO-263-2. 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 GND power_in Ground pin, the reference for the -5 V regulator (LM7905: output -4.82 V to -5.18 V).
2 INPUT power_in Negative unregulated input, shown as the shortened middle lead that is also marked as the tab INPUT; absolute maximum -35 V at TJ=25°C.
3 OUTPUT power_out Regulated negative output of -5 V (-4.82 V to -5.18 V) with output current in excess of 1.0 A.
