MIC49150YMM-TR from Microchip Tech, in a MSOP-8. 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 | EN/ADJ | input | On the adjustable MIC49150YMM this pin is the ADJ feedback input, connected to the resistor divider; the resistor between VOUT and ADJ should not exceed 10kΩ, as larger values can cause instability. The EN enable function applies only to fixed-output versions. |
| 2 | VBIAS | power_in | Bias supply powering all circuitry except the output power device, specified at 3V to 6.5V, and must be at least 1.6V above VOUT. |
| 3 | VIN | power_in | Input supply to the output power device, specified at 1.4V to 6.5V. |
| 4 | VOUT | power_out | Regulator output. |
| 5 | GND | power_in | Ground; pins 5 through 8 are joined to the die attach paddle for thermal and electrical conduction. |
| 6 | GND | power_in | Ground; pins 5 through 8 are joined to the die attach paddle for thermal and electrical conduction. |
| 7 | GND | power_in | Ground; pins 5 through 8 are joined to the die attach paddle for thermal and electrical conduction. |
