TLV704345DBVR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLV704345DBVR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TLV704345DBVR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 TLV704 series of low-dropout (LDO) regulators

are ultralow quiescent current devices designed for extremely power-sensitive applications. Quiescent

current is virtually constant over the complete load

current and ambient temperature range. These

devices are an ideal power-management attachment

to low-power microcontrollers, such as the MSP430.

The TLV704 operates over a wide operating input

voltage of 2.5 V to 24 V. Thus, the device is an

excellent choice for both battery-powered systems as

well as industrial applications that undergo large line

transients.

The TLV704 is available in a 3-mm × 3-mm SOT23-5

package, which is ideal for cost-effective board manufacturing.
