AS7805ADTR-E1

Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252-2

AS7805ADTR-E1 from Diodes Incorporated, in a TO-252-2. 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 INPUT power_in Unregulated voltage input; the AS7805A recommended input is 7.5 V to 20 V for regulation and up to 25 V maximum, with an absolute maximum of 36 V.
2 GND power_in Ground reference pin for the regulator, shared between input and output return.
3 OUTPUT power_out Regulated 5 V output, specified at 4.8 V to 5.2 V over the stated line, load and power-dissipation conditions, with output current up to 1 A.
