GENERAL DESCRIPTION
The AP1117C is a low-dropout linear regulator that operates in the input voltage range from +2.5V to
+7.0V and delivers 1A output current.
The AP1117C is available in two types, fixed output voltage type or adjustable output voltage type. The
fixed output voltage type is preset at an internally trimmed voltage 1.8V, 2.5V, or 3.3V. Other options 1.5V,
2.85V, 3.0V and 3.6V are available by special order only. The output voltage range of the adjustable type
is from 1.25V to 5V.
The AP1117C consists of a 1.25V bandgap reference, an error amplifier, and a P-channel pass
transistor. Other features include short-circuit protection and thermal shutdown protection. The AP1117C
devices are available in SOT-223 and TO-252 packages.
