LX8630-33CP集成电路（IC）的线性+开关稳压器规格书PDF中文资料

LX8630-33CP属于集成电路（IC）的线性+开关稳压器。由美高森美公司制造生产的LX8630-33CP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。

DESCRIPTION

The LX8630 family are positive very low dropout regulators. They are designed to provide a power supply for very low headroom applications, such as 3.3V – 2.5V.

BiCMOS technology allows an effective series pass element resistance, RDS(ON) of 150mΩ resulting in a typical dropout voltage of 450mV at 3A.

KEY FEATURES

◾ Dropout Voltage Typically 450mV at 3A and 50mV at 10mA

◾ Low Quiescent Current, Typically Under 400µA, irrespective of Load

◾ Shutdown Current 10µA

◾ Adjustable Output Version in 5-Pin TO-220 & TO-263 Packages

◾ Low Reverse Leakage Current

◾ Short-Circuit and Thermal Shutdown Protection

APPLICATIONS/BENEFITS

◾ 3.3V & 2.5V Supplies for Memory, Microprocessors, Clock Circuits, Etc.
