AIC1747-18GV5TR

AIC Analog Integrations · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

AIC1747-18GV5TR from AIC Analog Integrations, in a SOT-23-5. 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, operating over 2.0V to 6.0V, and the datasheet says to bypass it with a 1µF capacitor to GND.
2 GND power_in Ground pin, which also channels heat away from the device, so a large pad or ground plane lowers device temperature.
3 EN input Active-high enable input; the datasheet specifies VENH of 1.2V minimum for output ON and VENL of 0.4V maximum for output OFF (VIN = 2V to 6V).
4 BP passive Noise bypass pin, to be connected to an external 0.1nF capacitor to GND to reduce output noise.
5 VOUT power_out Regulator output pin that sources up to 300mA.
