LT3082EST#PBF

LINEAR TECHNOLOGY  LT3082EST#PBF  电压稳压器, LDO, 可调, 1.2V至40V输入, 1.3V压差, 0V至38.5V/0.2A输出, SOT-223-3

The is a 200mA Single Resistor Low Dropout Linear Regulator paralleled to increase output current or spread heat in surface mounted boards. Architected as a precision current source and voltage follower, this regulator benefits many applications requiring high current, adjustability to zero and no heat sink. The LT3082 withstands reverse input voltages and reverse output-to-input voltages without reverse-current flow. A key feature of the LT3082 is the capability to supply a wide output voltage range. A precision "0" TC 10µA reference current source drives a single resistor to program the output voltage to any level between zero and 38.5V. The LT3082 is stable with only 2.2µF of capacitance on the output and the IC uses small ceramic capacitors that do not require additional ESR as is common with other regulators. Internal protection circuitry includes reverse-battery and reverse-current protection, current limiting and thermal limiting.
