TPS75701KCG3集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS75701KCG3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TPS75701KCG3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 TPS757xx family of 3-A low dropout (LDO) regulators contains four fixed voltage option regulators with

integrated power-good (PG) and an adjustable voltage option regulator. These devices are capable of supplying

3 A of output current with a dropout of 150 mV (TPS75733). Therefore, the device is capable of performing a

3.3-V to 2.5-V conversion. Quiescent current is 125 μA at full load and drops down to less than 1 μA when the

device is disabled. The TPS757xx is designed to have fast transient response for large load current changes.
