BD18KA5WF-E2集成电路（IC）的线性+开关稳压器规格书PDF中文资料

BD18KA5WF-E2属于集成电路（IC）的线性+开关稳压器。由罗姆半导体集团制造生产的BD18KA5WF-E2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。

General Description

The BDxxKA5 series are low-saturation regulators that are available for output currents up to 500mA. The output voltage precision is ± 1. These LDO regulators are offered in several output voltages and package lineups with or without ON/OFF switches (that set the circuit current to 0μA at shutdown). This series can be used for a broad spectrum of applications ranging from TVs and car audio systems to HDDs, PCs, and DVDs. There regulators have a built-in overcurrent protection circuit that prevents the destruction of the IC, due to output short circuits and a thermal shutdown circuit.
