TPS76733QDR 低压差稳压器 TI德州原装

1 Features 2 Description

This device is designed to have a fast transient

1• 1 A Low-Dropout Voltage Regulator

response and be stable with 10 μF low ESR

• Available in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0- capacitors. This combination provides high

V, 3.3-V, 5.0-V Fixed Output and Adjustable performance at a reasonable cost.

Versions

Because the PMOS device behaves as a low-value

• Dropout Voltage Down to 230 mV at 1 A

resistor, the dropout voltage is very low (typically (TPS76750) 230 mV at an output current of 1 A for the TPS76750)

• Ultralow 85 μA Typical Quiescent Current and is directly proportional to the output current.

• Fast Transient Response Additionally, since the PMOS pass element is a

voltage-driven device, the quiescent current is very

• 2% Tolerance Over Specified Conditions for low and independent of output loading (typically Fixed-Output Versions 85 μA over the full range of output current, 0 mA to

• Open Drain Power-On Reset With 200-ms Delay 1 A). These two key specifications yield a significant

(See TPS768xx for PG Option) improvement in operating life for battery-powered

• 8-Pin SOIC and 20-Pin TSSOP PowerPAD™ systems. This LDO family also features a sleep

mode; applying a TTL high signal to EN (enable) (PWP) Package

shuts down the regulator, reducing the quiescent

• Thermal Shutdown Protection current to 1 μA at TJ = 25°C.

1特征2描述

本装置设计具有快速瞬态

1•1低压差稳压器

响应和稳定10μF低ESR

•可配置1.5-V、1.8-V、2.5-V、2.7-V、2.8-V、3.0-电容器。这种组合提供了很高的

V、3.3-V、5.0-V固定输出，性能可调，成本合理。

版本

因为PMOS器件的性能很低

•在1a点电压降至230 mV

在TPS76750的输出电流为1 A时，输出电压非常低(典型的(TPS76750) 230mv)

•85μA典型的超低静态电流和输出电流成正比。

•快速瞬态响应，因为PMOS通道元素是a

电压驱动装置，静止电流非常大

•2%公差超过指定条件低,独立于输出加载(通常输出固定版本85μA全方位的输出电流,0马

•开启排水渠通电复位，延迟200毫秒1秒)

(PG选项见TPS768xx)电池供电的使用寿命改善

•有SOIC和20-Pin TSSOP PowerPAD™系统。这个LDO家庭也有睡眠
