TLE4266-2G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 TLE 4266-2 is a monolithic integrated low-drop fixed voltage regulator which can supply loads up to 150 mA. It can be switched on and off by the INH pin. It is functional compatible to the TLE 4266, but with a reduced quiescent current of << 1 µ A in OFF mode and 40 µ A in ON mode. The TLE 4266-2 is especially designed for all applications that require very low quiescent current in ON and OFF mode. The device is available in the small surface mounted PG-SOT223-4 package. It is pin compatible to the TLE 4266 G. It is designed to supply microprocessor systems under the severe condition of automotive applications and therefore it is equipped with additional protection against over load, short circuit and overtemperature. Of course the TLE 4266-2 can be used in other applications, where a stabilized voltage and the inhibit feature is required. And input voltage VI up to 45 V is regulated to VQ = 5 V (TLE 4266-2 G) or VQ = 3.3 V (TLE 4266-2 GSV33) with an accuracy of ±3%. For the 5 V device an accuracy of ±2% is kept for a load current range  up to 50 mA. The device operates in the temperature range of T j = -40 to 150 °C. A high level at the INH pin switches the regulator on.

简介

TLE4266-2G属于集成电路（IC）的线性+开关稳压器。由制造生产的TLE4266-2G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。
