The AIC1117A-18GYTR is a SOT-223 RoHS compliant, low dropout regulator (LDO) manufactured by AIC. This device is designed to provide a stable, low-noise, low-voltage output power supply from a wide input range, and features an ultra-low dropout voltage (typically 0.18V at 300mA). Additionally, this regulator provides ripple rejection of up to 45dB, low ground current (typically 0.14mA at no-load), and an onboard frequency compensator. The AIC1117A-18GYTR is suitable for use in a wide range of applications including post-regulators, portable devices, LED drivers, etc.
