HANSCHIP semiconductor · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-220-3L
LM1084IT-ADJG from HANSCHIP semiconductor, 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/ADJ | power_in | Ground reference on fixed-voltage versions and the ADJ terminal on the adjustable LM1084-ADJ, where VOUT = VREF×(1+R2/R1)+IADJ×R2 with VREF of 1.250 V typical. |
| 2 | VOUT | power_out | Regulated output rated for up to 5 A, with 1.5 V dropout at 5 A and a 6.5 A typical current limit, and requires at least 22 μF tantalum output capacitance for stability. |
| 3 | VIN | power_in | Unregulated input supply with a 20 V absolute maximum and 12 V recommended input voltage. |
