LT3081ET7#PBF

LINEAR TECHNOLOGY  LT3081ET7#PBF  电压稳压器, LDO, 可调, 1.2V至36V输入, 1.23V压差, 0V至34.5V/1.5A输出, TO-220-7

The is a 1.5A Single Resistor Low Dropout Linear Regulator designed for rugged industrial applications. Key features of the IC are the extended safe operating area SOA, output current monitor, temperature monitor and programmable current limit. The LT3081 can be paralleled for higher output current or heat spreading. The LT3081"s precision 50µA reference current source allows a single resistor to program output voltage to any level between zero and 34.5V. The current reference architecture makes load regulation independent of output voltage. The LT3081 is stable with or without input and output capacitors. The output current monitor IOUT/5000 and die junction temperature output 1µA/°C provide system monitoring and debug capability. In addition, a single resistor programs current limit. Internal protection circuitry includes reverse-battery and reverse-current protection, current limiting and thermal limiting.
