MAX803ZEXR+T from 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. |
| 2 | RESET | output | Open-drain active-low reset output (MAX803) that remains low while VCC is below the reset threshold and for at least 140ms after VCC rises above it; requires a pullup resistor to any supply between 0 and 6V. |
| 3 | VCC | power_in | Supply voltage (+5V, +3.3V, +3.0V, or +2.5V) monitored by the reset circuit; absolute maximum -0.3V to +6.0V. |
