LDO Regulator, 200 mA, Ultra-High PSRR, with Tracking

Active

Overview

The NCV8182C is a monolithic integrated low dropout tracking regulator designed to provides an adjustable buffered output voltage that closely tracks the reference input.

The output delivers up to 250 mA while being able to be configured higher, lower or equal to the reference voltages. The device has been designed to operate over a wide input and VREF/EN operating voltage range while still maintaining excellent DC characteristics. The NCV8182C is protected from reverse battery, short circuit and thermal runaway conditions. The device also can withstand load dump transients and reverse polarity input voltage transients. This makes it suitable for use in automotive environments. The VREF/EN lead serves two purposes. It is used to provide the input voltage as a reference for the output and it also can be pulled low to place the device in sleep mode.
