AIC1747-33GV5TR

AIC Analog Integrations · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

AIC1747-33GV5TR from AIC Analog Integrations, in a SOT-25. 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 VIN power_in Power supply input pin; bypass with a 1µF capacitor to GND, with input voltage specified from 2V to 6V and an absolute maximum of 7V.
2 GND power_in Ground pin, which also channels heat away from the device, so a large ground pad or plane is recommended.
3 EN input Active-high enable input; the enable threshold is 1.2V minimum for ON and 0.4V maximum for OFF, with an absolute maximum EN pin voltage of 7V.
4 BP passive Bypass pin; connect to an external 0.1nF capacitor to GND to reduce output noise, with an absolute maximum terminal voltage of 7V.
5 VOUT power_out Regulator output pin that sources up to 300mA.
