The PL1084A-XXXF3 is a low dropout three terminal regulator with 5A output current capability. The output voltage is
adjustable with the use of a resistor divider or fixed 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V. Dropout voltage is guaranteed to be at
maximum of 1.5V with the maximum output current. Its low dropout voltage and fast transient response make it ideal for
low voltage microprocessor applications. Current limit and thermal protection provide protection against any overload
condition that would create excessive junction temperatures.
