GR7336-A

GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

GR7336-A 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 GND power_in Chip ground terminal (芯片接地端) for the GR73xx LDO regulator in the SOT89-3 package.
2 VIN power_in Start-up/input terminal (启动输入端); the datasheet rates the input voltage up to 15 V, with an absolute maximum input voltage of 18 V.
3 VOUT power_out Chip output terminal (芯片输出端) providing the regulated output voltage, which is 3.6 V with ±3% tolerance for GR7336-A.
