Product Overview

The LT3086ET7#PBF is an Adjustable 2.1A Low Dropout Linear Regulator with monitoring and cable drop compensation that operates over a 1.4 to 40V input supply range. Dropout voltage at 2.1A is typically 330mV. One resistor sets output voltage from 0.4 to 32V. Output voltage tolerance is guaranteed to ±2% over line, load and temperature. It is stable with ceramic output capacitors, requiring a minimum of 10µF. The LT3086's programmable cable drop compensation cancels output voltage errors caused by resistive connections to the load. A master/slave configuration allows paralleling of multiple devices for higher load current and heat spreading without external ballast resistor requirements. Output current and temperature monitoring along with a power good flag provide system diagnostic and debug capability. Internal fault circuitry includes thermal shutdown and current limit with fold back. Thermal limit and current limit are also externally programmable.
