LT®3080-1 是一款 1.1A 低压差线性稳压器,它包含一个内部镇流电阻器,以在无需 PC 板走线电阻器的情况下实现器件的直接并联。内部镇流电阻器允许在表面安装型电路板上直接并联多个器件,以提供较高输出电流和散热量,同时使电路板布局简单而容易。该器件将传输晶体管的集电极引出,以实现低压差 (低至 350mV) 运作 (当与多个输入电源一起使用)。

LT3080-1 能够提供一个宽输出电压范围。流过单个电阻器的一个基准电流用于把输出电压设置在 0V 至 36V 之间的任何电平。当在输出端上使用 2.2μF 陶瓷电容时,LT3080-1 可实现稳定,而不像其他稳压器所常见的那样需要额外的 ESR。

内部保护功能包括电流限制和热限制。LT3080-1 稳压器采用 8 引脚 MSOP (具有一个裸露衬垫,用于改善热特性) 和 3mm x 3mm DFN 封装。



Applications

  • 高电流全表面安装型电源
  • 高效率线性稳压器
  • 用于开关电源的后置稳压器
  • 低元件数目可变电压电源
  • 低输出电压电源

产品详情

Demonstration circuit 1368A exercises four adjustable linear regulators in parallel using the LT3080-1, which incorporates an internal ballast resistor. The ballast resistor allows direct paralleling of devices without the need for PC board resistors or sensor resistors.The paralleled devices provide up to 4.4A of output current at 1.2V.


Architected as a precision current source and voltage follower, the LT3080-1 can be used in many applications requiring high current, adjustability to zero output, and no heat sink. The device brings out the collector of the pass transistor to allow low dropout operation when used with multiple supplies. The LT3080-1's output voltage can be programmed to any level between 0V and 36V; however the demo board has a reduced input voltage range from 1.7V to 25V due to the input capacitor voltage rating.
