MC78M12AB集成电路（IC）的线性+开关稳压器规格书PDF中文资料

MC78M12AB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MC78M12AB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。

描述 Description

The MC78M00/MC78M00A Series positive voltage regulators are

identical to the popular MC7800 Series devices, except that they are

specified for only half the output current. Like the MC7800 devices,

the MC78M00 threeïterminal regulators are intended for local,

onïcard voltage regulation.

Internal current limiting, thermal shutdown circuitry and safeïarea

compensation for the internal pass transistor combine to make these

devices remarkably rugged under most operating conditions.

Maximum output current, with adequate heatsinking is 500 mA.
