AIC1117A-25GYTR

AIC Analog Integrations · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

AIC1117A-25GYTR from AIC Analog Integrations, in a SOT-223. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Power ground (device common). On the fixed-voltage AIC1117A-25 version, pin 1 is GND (this pin is the ADJ pin on the adjustable variant).
2 VOUT power_out Regulated 2.5V output (2.47V min, 2.50V typ, 2.53V max at VIN=5V). Delivers up to 1A. Also connected to the SOT-223 thermal tab. Requires a minimum 10µF (aluminum electrolytic recommended) capacitor to GND for stability.
3 VIN power_in Unregulated positive supply input. Must be at least VOUT + 1.3V (typical dropout at 1A). Absolute maximum VIN-to-GND is 7V. A 10µF input capacitor is recommended if the device is far from the bulk filter capacitors.
