1.General Description
RY1117B is a series of low dropout three-terminal regulators with a dropout of 1.3V at 1A load current. RY1117B
features a very low standby current 2mA compared to 5mA of competitor.
Other than a fixed version, VOUT = 1.2V, 1.5V, 1.8V, 2.5V, 2.85V, 3.3V, and 5V, RY1117B has an adjustable version,
which can provide an output voltage from 1.25 to 12V with only two external resistors.
RY1117B offers thermal shut down function, to assure the stability of chip and power system. It uses trimming
technique to guarantee output voltage accuracy within 2%. Other output voltage accuracy can be customized on
demand, such as 1%.
RY1117B is available in SOT-223, TO-252, SOT-89 power package.
