DESCRIPTION
The AMC317 series is a 3-terminal adjustable regulator
featuring output current of typical 1.2A over a wide output
range from 1.2V to 20V. Only two external resistors are
required to set the output voltage. This feature provides
better line and load regulation than fixed regulators.
Also, the AMC317 series offers full overload
protection, current limit, and thermal protection features. In
most applications, no capacitor is required for the AMC317.
However, if the device is located far from the input filter
capacitor, then an input bypass will be required. Also, in
order to improve the transient response, an output capacitor
is recommended.
