IKSEMICON · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TO-252
IL1117C-5.0D0T from IKSEMICON, in a TO-252. 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 | Adjust terminal on adjustable versions, where VREF is 1.25V between VOUT and ADJ and the adjust pin current is 56 to 80 uA typical/max at Io = 10mA; on fixed versions this pin is the ground return. |
| 2 | Output | power_out | Regulated output that needs a minimum 10uF tantalum capacitor to VOUT-to-GND for stability and transient response; the tab is electrically connected to this pin, so isolate it with a thermally conductive spacer if the heat sink must be isolated. |
| 3 | Input | power_in | Unregulated input supply with a maximum input voltage of 15V, where a 10uF tantalum input bypass capacitor is suitable for almost all applications. |
