**Microchip Tech** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8-EP

MIC69153YME-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 pin for the regulator; the datasheet's exposed-pad guidance (connect to ground) is stated for the DFN package. |
| 2 | EN | input | CMOS-compatible enable input where logic-high enables and logic-low shuts down the regulator, with EN limited to 0V to VIN and not to be left floating. |
| 3 | VIN | power_in | Input voltage that supplies current to the output power device, specified from 1.65V to 5.5V. |
| 4 | VIN | power_in | Input voltage that supplies current to the output power device, specified from 1.65V to 5.5V; pins 3 and 4 are both VIN. |
| 5 | VOUT | power_out | Regulator output, adjustable from 0.5V to 5.5V with an external resistor divider. |
| 6 | VOUT | power_out | Regulator output, adjustable from 0.5V to 5.5V with an external resistor divider; pins 5 and 6 are both VOUT. |
| 7 | ADJ | input | Adjustable regulator feedback input (VFB nominally 0.5V) connected to the resistor divider; the resistor between VOUT and ADJ should not exceed 10 kΩ. |
| 8 | FLG | output | Open-collector error flag output that goes active-low to indicate an output fault condition, with a +6V absolute maximum rating. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
