L5150CS中文资料5V低压降稳压器数据手册ST规格书

描述 Description

L5150CJ and L5150CS are low dropout linear regulators with microprocessor control functions such as power on reset, low voltage reset, early warning.

Typical quiescent current is 55 μA at very low output current.

On chip trimming results in high output voltage accuracy (±2%). Accuracy is kept over wide temperature range, line and load variation. Early warning circuit monitors the input voltage and compares it with an internal voltage reference.

Output voltage reset threshold can be adjusted down to 3.5 V by means of an external voltage divider.

The maximum input voltage is 40 V. The max output current is internally limited. Internal temperature protection disables the voltage regulator output. In addition, only low-value ceramic capacitor on output is required for stability.

简介

L5150CS属于集成电路（IC）的线性+开关稳压器。由制造生产的L5150CS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。
