MIC37102数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The MIC37100, MIC37101, and MIC37102 are 1A low dropout, linear voltage regulators that provide low-voltage, high-current output from an extremely small package. Utilizing proprietary Super βeta PNP® pass element, the MIC37100/01/02 offers extremely low dropout (typically 280mV at 1A) and low ground current (typically 11mA at 1A).The MIC37100 is a fixed output regulator offered in the SOT-223 package. The MIC37101 and MIC37102 are fixed and adjustable regulators, respectively, in a thermally enhanced power 8-pin SOIC (small outline package) and the SOT-223 package. The MIC37102 is also available in the S-PAK power package for applications that require higher power dissipation or higher operating ambient temperatures.The MIC37100/01/02 is ideal for PC add-in cards that need to convert from standard 5V to 3.3V, 3.3V to 2.5V, or 2.5V to 1.8V or lower. A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the MIC37100/01/02 to provide 2.5V from a supply as low as 3V and 1.8V from a supply as low as 2.3V.The MIC37100/01/02 is fully protected with overcurrent limiting and thermal shutdown. Fixed output voltages of 1.5V, 1.65V, 1.8V, 2.5V, and 3.3V are available on MIC37100/01 with adjustable output voltages to 1.24V on MIC37102.

简介

MIC37102属于集成电路（IC）的线性+开关稳压器。由制造生产的MIC37102稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
