The IP1117 is a series of low dropout voltage regulators which can provide up to 1A of output current. The IP1117 is available in four fixed voltages, 1.8V, 2.5V, 2.85V, 3.3V and 5.0V. Additonally it is also available in adjustable version. On chip precision trimming adjusts the refernce/output voltage to within 2%. Current limit is also trimmed to ensure specified output current and controlled short-circuit current. The IP11117 series is available in SOT-223 and DPAK power packages. A minimum of 10uF tantalum capacitor is required at the output to improve the transient response and stability.
