MC78T12AC集成电路（IC）的线性+开关稳压器规格书PDF中文资料

MC78T12AC属于集成电路（IC）的线性+开关稳压器。由安森美半导体公司制造生产的MC78T12AC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。

3.0 A Positive Voltage Regulators

This family of fixed voltage regulators are monolithic integrated circuits capable of driving loads in excess of 3.0 A. These three−terminal regulators employ internal current limiting, thermal shutdown, and safe−area compensation. Devices are available with improved specifications, including a 2 output voltage tolerance, on AC−suffix 5.0 V, 12 V and 15 V device types.

Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. This series of devices can be used with a series−pass transistor to supply up to 15 A at the nominal output voltage.
