DESCRIPTION
The LM1086 is a low dropout three terminal regulators with 1.5A output current capability.
The output voltage is adjustable with the use of a resistor divider. Dropout is guaranteed at a maximum
of 500 mV at maximum output current.
It's low dropout voltage and fast transient response make it ideal for low voltage microprocessor
applications. Internal current and thermal limiting provides protection against any overload condition
that would create excessive junction temperature.
