EA8273T7R from Everanalog IC design, in a SOT-563. 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 | PWR | power_in | Power input pin for the regulator, operating from 4.5V to 16V with an absolute maximum of -0.3V to +17V; two 10uF MLCC capacitors are recommended between PWR and GND. |
| 2 | SWITCH | output | Internal MOSFET switching output that must be connected through a low-pass filter to obtain a stable DC output; the absolute maximum SWITCH pin voltage is -1V to +17.5V. |
| 3 | GND | power_in | Ground pin. |
| 4 | BOOT | power_in | Power input for the internal high-side N-MOSFET gate driver; connect a 33nF ceramic capacitor from BOOT to SWITCH, with BOOT voltage limited to VSWITCH-0.3V to VSWITCH+5V. |
| 5 | RUN | input | On/off control input: above 1.2V (typ.) enables the regulator and below 0.4V shuts it down; the absolute maximum rating is -0.3V to +6.3V, and it may be tied to PWR through a 150kΩ resistor for automatic startup but must not be shorted directly to PWR. |
| 6 | FBK | input | Feedback input that connects through a resistor divider between the output and GND to set the output voltage, with a reference of 0.807V typ. (0.791V to 0.823V) and an absolute maximum of -0.3V to +6.3V. |
