LT3086ET7#PBF

LINEAR TECHNOLOGY  LT3086ET7#PBF  电压稳压器, LDO, 可调, 1.4V至40V输入, 330mV压差, 400mV至32V/2.1A输出, TO-220-7

The 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.
