MC79L12ACLPR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

MC79L12ACLPR属于集成电路（IC）的线性+开关稳压器。由德州仪器制造生产的MC79L12ACLPR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。

description/ordering information

This series of fixed negative-voltage

integrated-circuit voltage regulators is designed

for a wide range of applications. These include

on-card regulation for elimination of noise and

distribution problems associated with single-point

regulation. In addition, they can be used to control series pass elements to make high-current voltage-regulator

circuits. One of these regulators can deliver up to 100 mA of output current. The internal current-limiting and

thermal-shutdown features essentially make the regulators immune to overload. When used as a replacement

for a Zener-diode and resistor combination, these devices can provide an effective improvement in output

impedance of two orders of magnitude, with lower bias current.
