L7905-1.5A

TDSEMIC · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3L

L7905-1.5A from TDSEMIC, in a TO-220-3L. 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 Common ground reference for the regulator; the datasheet gives no separate voltage or current limit for this pin.
2 IN power_in Negative unregulated input voltage, with an absolute maximum of -35 V, and the datasheet's electrical characteristics are specified at Vi = -10 V with Ci = 2.2 μF.
3 OUT power_out Regulated negative output of nominally -5 V (-4.8 V to -5.2 V at 25 ℃), rated for output current up to 1.2 A and used with Co = 1 μF.
