MC33275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 MC33275 series are micropower low dropout (LDO) linear voltage regulators available in a wide variety of output voltages as well as packages, DPAK, SOT-223, and SOP-8 surface mount packages. These devices feature a very low quiescent current and are capable of supplying output currents up to 300 mA. Internal current and thermal limiting protection are provided by the presence of a short circuit at the output and an internal thermal shutdown circuit.The MC33275 is available as a MC33375 which includes an On/Off control.Due to the low input-to-output voltage differential and bias current specifications, these devices are ideally suited for battery powered computer, consumer, and industrial equipment where an extension of useful battery life is desirable.

特性 Features

• Low Quiescent Current (125 mA)
• Low Input-to-Output Voltage Differential of 25 mV at IO = 10mA, and 260 mV at IO = 300 mA
• Extremely Tight Line and Load Regulation
• Stable with Output Capacitance of only 0.33 mF for 2.5 V Output Voltage
• Internal Current and Thermal Limiting

应用 Application

• Battery Powered Consumer Products
• HandHeld Instruments
• Camcorders and Cameras

简介

MC33275属于集成电路（IC）的线性+开关稳压器。由制造生产的MC33275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。
