描述 Description

The CBM1117C is a series of low dropout voltage regulators which can provide up to 1A of output cur-rent.  The CBM1117C is available in eight fixed voltage, 1.2, 1.25, 1.5, 1.8, 2.5, 2.85, 3.3 and 5.0V. Additionally it is also available in adjustable version. On chip precision trimming adjusts the reference/ output voltage to within ± 2%. Current limit is also trimmed to ensure specified output current and controlled short-circuit current.

The CBM1117C series is available in SOT-223, TO-252, TO-263 packages.

A minimum of 10uF tantalum capacitor is required at the output to improve the transient response and Stability.
