TPS767D3集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS767D3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TPS767D3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 TPS767D3xx family of dual voltage regulators offers fast transient response, low dropout voltages and dual

outputs in a compact package and incorporating stability with 10-μF low ESR output capacitors.

The TPS767D3xx family of dual voltage regulators is designed primarily for DSP applications. These devices

can be used in any mixed-output voltage application, with each regulator supporting up to 1 A. Dual active-low

reset signals allow resetting of core-logic and I/O separately.
