TPS7430集成电路（IC）的稳压器-线性规格书PDF中文资料

TPS7430属于集成电路（IC）的稳压器-线性。由德州仪器制造生产的TPS7430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

This device is designed to have a fast transient response and be stable with 1-mF capacitors. This combination

provides high performance at a reasonable cost.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 170 mV

at an output current of 200-mA for the TPS7433). This LDO family also features a sleep mode; applying a TTL

high signal to EN (enable) shuts down the regulator, reducing the quiescent current to less than 1 mA at

TJ = 25°C.

The TPS74xx is offered in 1.5-V, 1.8-V, 2.5-V, 3-V, and 3.3-V. Output voltage tolerance is specified as a

maximum of 3% over line, load, and temperature ranges. The TPS74xx family is available in 8 pin SOIC

package.
