TLV704345DBVT集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLV704345DBVT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TLV704345DBVT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 low-dropout (LDO) linear voltage

regulator is a low quiescent current device that

offers the benefits of a wide input voltage range

and low-power operation in miniaturized packaging.

Thus, the TLV704 is designed for battery-powered

applications and as a power-management attachment

to low-power microcontrollers.

The TLV704 LDO supports a low dropout of typically

850 mV at 100 mA of load current. The low quiescent

current (3.4 μA typically) is stable over the entire

range of output load current (0 mA to 150 mA). The

TLV704 also features an internal soft-start to lower the

inrush current. The built-in overcurrent limit protection

helps protect the regulator in the event of a load short

or fault.

The TLV704 is available in a 2.90-mm × 1.60-mm

SOT23-5 package, which is useful for cost-effective

board manufacturing.
