TPS70925QDRVRQ1集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS70925QDRVRQ1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TPS70925QDRVRQ1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。

3 Description

The TPS709-Q1 series of linear regulators are ultralow,

quiescent current devices designed for powersensitive

applications. A precision band-gap and error

amplifier provides 2% accuracy over temperature.

Quiescent current of only 1μA makes these devices

designed for battery-powered, always-on systems that

require very little idle-state power dissipation. These

devices have thermal-shutdown, current-limit, and

reverse-current protections for added safety.

These regulators can be put into shutdown mode by

pulling the EN pin low. The shutdown current in this

mode goes down to 150nA, typical.

The TPS709-Q1 series is available in WSON-6 and

SOT-23-5 packages.
