TPS7348QDR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS7348QDR属于集成电路（IC）的线性+开关稳压器。由德州仪器制造生产的TPS7348QDR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 TPS73xx devices are members of a family of

micropower low-dropout (LDO) voltage regulators.

They are differentiated from the TPS71xx and TPS72xx LDOs by their integrated delayed microprocessor-reset

function. If the precision delayed reset is not required, the TPS71xx and TPS72xx should be considered
