UA7905CKTTR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

UA7905CKTTR属于集成电路（IC）的线性+开关稳压器。由美国德州仪器公司制造生产的UA7905CKTTR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/ORDERING INFORMATION

This series of fixed-negative-voltage integrated-circuit voltage regulators is designed to complement Series

mA7900 in a wide range of applications. These applications include on-card regulation for elimination of noise

and distribution problems associated with single-point regulation. Each of these regulators can deliver up to

1.5 A of output current. The internal current limiting and thermal shutdown features of these regulators

essentially make them immune to overload. In addition to use as fixed-voltage regulators, these devices can be

used with external components to obtain adjustable output voltages and currents and also as the power-pass

element in precision regulators.
