TPS7A7300RGWT集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS7A7300RGWT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TPS7A7300RGWT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 TPS7A7300 low-dropout (LDO) voltage regulator

is designed for applications requiring very-low dropout

capability (240 mV at 3 A) with an input voltage from

1.5 V to 6.5 V. The TPS7A7300 offers an innovative,

user-configurable, output-voltage setting from 0.9 V

to 3.5 V, thus eliminating external resistors and any

associated errors.

The TPS7A7300 has very fast load-transient

response, is stable with ceramic output capacitors,

and supports a better than 2% accuracy over

line, load, and temperature. A soft-start pin allows

for an application to reduce inrush into the load.

Additionally, an open-drain, power-good signal allows

for sequencing power rails.

The TPS7A7300 is available in a 5-mm × 5-mm, 20-

pin VQFN package.
