LINEAR TECHNOLOGY  LT3086IDHD#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, DFN-16

The is a multi-feature low noise low-dropout Linear Regulator 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. The LT3086 is stable with ceramic output capacitors, requiring a minimum of 10µF. The LT3086 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.
