# AIC1084GMTR

**AIC(Analog Integrations)** · Linear Voltage Regulators (LDO) · TO-263-2

AIC1084GMTR from AIC(Analog Integrations), 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 | ADJ (GND) | power_in | The ADJ pin provides VREF=1.25V (typ.) for adjustable VOUT, with IADJ=55µA (typ.) and VREF=VOUT-VADJ, and it is the power ground reference. |
| 2 | VOUT (TAB) | power_out | The VOUT pin, which is also the tab, delivers the adjustable output voltage up to 5A output current with 1.5V maximum dropout. |
| 3 | VIN | power_in | The VIN pin is the power input, with VIN to ADJ/GND absolute maximum rated at 7V. |
