CS8147集成电路（IC）的线性+开关稳压器规格书PDF中文资料

CS8147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CS8147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。

The CS8147 is a 10 V/5.0 V dual output linear regulator. The 10V ±5.0 output sources 500 mA and the 5.0 V ±3 output sources 70 mA. The secondary output is inherently stable and does not require an external capacitor.

The on board ENABLE function controls the regulator’s two outputs. When ENABLE is high, the regulator is placed in SLEEP mode. Both outputs are disabled and the regulator draws only 70 µA of quiescent current.

The regulator is protected against overvoltage conditions. Both outputs are protected against short circuit and thermal runaway conditions.

The CS8147 is packaged in a 5 lead TO–220 with copper tab. The copper tab can be connected to a heat sink if necessary.
