TC1301A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 TC1301A/B combines two Low Drop Out (LDO) regulators and a microcontroller RESET function while the TC1302A/B is purely a dual LDO. Both parts are available in single 8-pin MSOP or DFN package. The TC1301A/B & TC1302A/B features low dropout voltages as low as 104mV @ 300mA, low quiescent current consumption at 116 µA typical and a voltage output accuracy of +/- 0.5%. Several fixed output voltage and detector voltage combinations are available. A reference bypass pin is available for TC1301A/B to further reduce output noise and improve the power supply rejection ratio of both LDOs. The TC1301A/B & TC1302A/B is stable over all line and load conditions with a minimum of 1 µF of ceramic output capacitance and utilizes a unique compensation scheme to provide fast dynamic response to sudden line voltage and load current changes.

简介

TC1301A属于集成电路（IC）的线性+开关稳压器。由制造生产的TC1301A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。
