TPS75925KC集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS75925KC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TPS75925KC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 TPS759xx family of 7.5-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

7.5 A of output current with a dropout of 400 mV (TPS75933). Therefore, the devices are capable of performing a

3.3-V to 2.5-V conversion. Quiescent current is 125 μA at full load and drops below 10 μA when the devices are

disabled. The TPS759xx is designed to have fast transient response for large load current changes.
