LT3082 200mA Single Resistor Low Dropout Linear Regulator FEATURES n n n n n n n n n n n n n n DESCRIPTION The LT®3082 is a 200mA low dropout linear regulator that can be 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; 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. The LT3082 is offered in the thermally enhanced 8-lead TSOT-23, 3-lead SOT-223 and 8-lead 3mm × 3mm DFN packages.

器件简介: LT3082是一款200mA低 dropout 线性调节器,可以并联使用以增加输出电流或在表面贴装板上分散热量。该调节器作为精密电流源和电压跟随器,具有很多应用,包括需要高电流、可调至零和无需散热器的应用。LT3082能够承受反向输入电压和反向输出至输入电压而不产生反向电流流动。

引脚分配: - IN (Pins 7, 8/Pin 3/Pins 7, 8): 输入引脚,为内部电路提供电源并输出负载电流。 - SET (Pin 4/Pin 1/Pin 5): 设置引脚,用于设定输出电压。 - OUT (Pins 1, 2/Pin 2/Pins 2, 3, 4): 输出引脚,设备的电源输出。 - Exposed Pad/Tab (Pin 9/Tab/NA): 暴露的垫/标签,DFN封装的暴露垫和SOT-223封装的标签在内部与OUT引脚相连。

参数特性: - 输出电流可达200mA。 - 宽输入电压范围:1.2V至40V。 - 输出可调至0V。 - 稳定工作只需最小2.2μF陶瓷电容。 - 单一电阻设置输出电压。 - 初始设定引脚电流精度为1%。 - 低输出噪声:33μVRMS (10Hz至100kHz)。 - 反向电池保护和反向电流保护。 - 典型负载调节:<0.001%/V。 - 电流限制和热关断保护。

功能详解: LT3082通过一个精确的“0”TC 10μA参考电流源驱动单个电阻来设置输出电压,可在零到38.5V之间任意调节。内部保护电路包括反向电池和反向电流保护、电流限制和热限制。

应用信息: - 适用于所有表面贴装电源。 - 开关电源后的调节器。 - 低元件数量的可变电压供应。 - 低输出电压供应。 - 电池供电调节器。

封装信息: - 8引脚SOT-23、3引脚SOT-223和8引脚3mm×3mm DFN封装。
