Microchip Tech · Linear Voltage Regulators (LDO) · SOIC-8-EP
MIC69303YME-TR from Microchip Tech, in a SOIC-8-EP. 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 | Ground. |
| 2 | EN | input | Enable input, CMOS compatible: logic high enables the regulator, logic low shuts it down, and the pin must not be left floating. |
| 3 | IN | power_in | Input voltage (1.65V to 5.5V) that supplies current to the output power device; pins 3 and 4 are both IN. |
| 4 | IN | power_in | Input voltage (1.65V to 5.5V) that supplies current to the output power device; pins 3 and 4 are both IN. |
| 5 | OUT | power_out | Regulator output; pins 5 and 6 are both OUT. |
| 6 | OUT | power_out | Regulator output; pins 5 and 6 are both OUT. |
| 7 | ADJ | input | Adjustable regulator feedback input (0.5V reference) that connects to a resistor voltage divider, with the resistor from OUT to ADJ not exceeding 10kΩ. |
| 8 | FLG | output | Error flag, open collector output that is active low to indicate an output fault condition. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
