TLV7111812DSER集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLV7111812DSER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TLV7111812DSER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

The TLV710 and TLV711 series of dual, low-dropout

(LDO) linear regulators are low quiescent current

devices with excellent line and load transient

performance. These LDOs are designed for

power-sensitive applications. These devices provide

a typical accuracy of 2% over temperature.

The TLV711 series provides an active pulldown

circuit to quickly discharge the outputs.

In addition, the TLV711-D series of devices have

pull-down resistors at the EN pins. This design helps

in disabling the device when the signal-driving EN

pins are in a weak, indeterminate state (for example,

the GPIO of a processor that might be three-stated

during startup). The pull-down resistor pulls the

voltage to the EN pins down to 0V, thus disabling the

device.

The TLV710 and TLV711 series are available in a

1.5mm x 1.5mm SON-6 package, and are ideal for

handheld applications.
