GR7033A

GR · Supervisor And Reset ICs · SOT-89-3

GR7033A from GR, in a SOT-89-3. 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 OUT output Chip output terminal; the output voltage is limited to GND-0.3 V to VDD+0.3 V, and the datasheet gives a minimum IOL of 0.5 mA (typical 1 mA) at VDD = 2 V with VOUT = 0.2 V.
2 VDD power_in Chip supply input; the operating voltage range is 1.5 V to 12 V, and the absolute maximum input voltage is 15 V.
3 GND power_in Chip ground terminal; the datasheet gives no additional electrical limit for this pin.
