MIC37501中文资料5A Low Voltage LDO Regulator数据手册Microchip规格书

描述 Description

The MIC37501 and MIC37502 are 5A, low dropout linear voltage regulators that provide low-voltage, high-current outputs with a minimum of external components. They offer high precision, ultra-low dropout (500mV), and low ground current. The MIC37501and MIC37502 operate from an input of 2.3V to 6.0V. They are designed to drive digital circuits requiring low voltage at high currents (i.e., PLDs, DSPs, microcontrollers, etc.). They are available in fixed and adjustable output voltages. Fixed voltages include 1.5V, 1.65V, 1.8V, 2.5V, and 3.3V. The adjustable version is capable of 1.24V to 5.5V. MIC37501 and MIC37502 LDOs feature thermal and current limit protection, and reverse current protection. Logic-enable and error flag pins are available. Junction temperature range of the MIC37501/02 is -40°C to 125°C. For applications requiring input voltage greater than 6.0V, see MIC3910x, MIC3915x, MIC3930x, and MIC3950x LDOs.

简介

MIC37501属于集成电路（IC）的线性+开关稳压器。由Microchip制造生产的MIC37501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。
