TLE42994GM数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

An input voltage up to 45 V is regulated to an output voltage of 5.0 V. The component is able to drive loads up to 150 mA. It is short-circuit protected by the implemented current limitation and has an integrated overtemperature shutdown. A reset signal is generated for an output voltage VQ,rt of typically 4.65 V.This threshold can be decreased by an external resistor divider. The power-on reset delay time can be programmed by the external delay capacitor. The additional sense comparator provides an early warning function: Any voltage (e.g. the input voltage) can be monitored, an undervoltage condition is indicated by setting the comparator’s output to low. TLE42994E, PG-SSOP-14 exposed pad package, has an Enable function permitting enabling/disabling the regulator. In case the regulator is disabled it consumes less current than 1 µA.

简介

TLE42994GM属于集成电路（IC）的线性+开关稳压器。由制造生产的TLE42994GM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。
