MAX803TEXR+T from Analog Devices Inc Maxim Integrated, in a SC-70-3. 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 reference for the device; all terminal voltage limits are specified with respect to GND. |
| 2 | RESET | output | Open-drain active-low reset output that stays low while VCC is below the reset threshold and for at least 140ms after VCC rises above it, and requires a pullup resistor to any supply between 0 and 6V. |
| 3 | VCC | power_in | Supply voltage monitored by the reset comparator (+5V, +3.3V, +3.0V, or +2.5V nominal), specified at 1.2V to 5.5V for the EXR version over -40°C to +125°C. |
