The AIC1117-18GYTR Low Dropout Regulator (LDO) is a SOT-223 RoHS device manufactured by AIC that offers adjustable output voltage, low dropout voltage, high power supply noise rejection, low quiescent current, thermal shutdown over-temperature protection, and low output voltage noise. It is a one-time programmable device and allows for precise voltage adjustment from 0.8V to 5.0V with 1.5mV increments. It operates with a maximum output current of 1.3A and features a PMOS internal pass transistor that helps with power saving. Additionally, its SOT-223 package features high current with decent thermal performance and is compatible for use with a variety of applications due to its fast transient response, low noise, and high output loading capability.
