TPS7A1633DRBT集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TPS7A1633DRBT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TPS7A1633DRBT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 TPS7A16 family of ultralow power, low-dropout

(LDO) voltage regulators offers the benefits of ultra- low quiescent current, high input voltage and

miniaturized, high thermal-performance packaging.

The TPS7A16 family is designed for continuous or

sporadic (power backup) battery-powered

applications where ultralow quiescent current is

critical to extending system battery life.

The TPS7A16 family offers an enable pin (EN)

compatible with standard CMOS logic and an integrated open drain active-high power good output

(PG) with a user-programmable delay. These pins are

intended for use in microcontroller-based, battery•

powered applications where power-rail sequencing is

required.

In addition, the TPS7A16 is ideal for generating a

low-voltage supply from multicell solutions ranging

from high cell-count power-tool packs to automotive

applications; not only can this device supply a well-

regulated voltage rail, but it can also withstand and

maintain regulation during voltage transients. These

features translate to simpler and more cost-effective,

electrical surge-protection circuitry.
