TPS79618DCQ集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS79618DCQ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TPS79618DCQ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 TPS796 low-dropout (LDO) low-power linear

voltage regulator features high power-supply rejection

ratio (PSRR), low-noise, fast start-up, and excellent

line and load transient responses in small outline,

3mm × 3mm VSON, SOT223-6, and TO-263

packages. Tis device is stable with a small, 1μF

ceramic capacitor on the output. The TPS796 offers

low dropout voltages (for example, 220mV at 1A).

Applications with analog components that are noise

sensitive (such as portable RF electronics) benefit

from the high-PSRR, low-noise features, and need

fast response time.
