Description
The PL1085-XXXE3 is a low dropout three terminal regulator with 3A output current capability. The output voltage is
adjustable with the use of a resistor divider or fixed 1.5V, 1.8V, 2.5V, 2.85V, 3.0V, 3.3V, 3.5V and 5.0V. Dropout voltage is
guaranteed to be at maximum of 1.3V 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.
