CS8321YDPR3集成电路（IC）的线性+开关稳压器规格书PDF中文资料

CS8321YDPR3属于集成电路（IC）的线性+开关稳压器。由安森美半导体制造生产的CS8321YDPR3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。

Micropower 5.0 V, 150 mA Low Dropout Linear Regulator

The CS8321 is a precision 5.0 V micropower voltage regulator with very low quiescent current (140 A typ at 1.0 mA load). The 5.0 V output is accurate within ±2 and supplies 150 mA of load current with a typical dropout voltage of only 300 mV.

This combination of low quiescent current and outstanding regulator performance makes the CS8321 ideal for any battery operated equipment.

The regulator is protected against reverse battery and short circuit conditions. The device can withstand 45 V load dump transients making it suitable for use in automotive environments.
