L4892集成电路（IC）的线性+开关稳压器规格书PDF中文资料

L4892属于集成电路（IC）的线性+开关稳压器。由意法半导体集团制造生产的L4892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

L4800 series devices are voltage regulators with a very low voltage drop (typically 0.4V at full rated current), output current up to 400mA, low quiescent current and comprehensiveon-chip protection.The se devices are protected against load dump and field decay transients of±60V, polarity reversal and overheating. A foldback current limiter protects against load short circuits. Available in 5V, 8.5V, 9.2V,10V and12Vversions (all±4,TI=25°C) the se regulators aredesigned for automotive, industrial and consumer applications where low consumption is particularly important.
