Datasheet
This device is designed to have a fast transient response and be stable with 10-µF low ESR 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 230 mV at an output current of 1 A for the TPS76850) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85 µA over the full range of output current, 0 mA to 1 A). These two key specifications yield a significant improvement in operating life for battery-powered systems. 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 µA at TJ = 25°C.
Power good (PG) is an active high output, which can be used to implement a power-on reset or a low-battery indicator.
The TPS768xx is offered in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, and 5.0-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.2 V to 5.5 V). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges. The TPS768xx family is available in a 20-pin PWP package.
德克萨斯仪器tps76801qpwprepthis装置设计有一个快速的瞬态响应和稳定10µF低ESR电容。这种组合以合理的成本提供高性能。
由于PMOS器件作为一个低电阻值表现，辍学电压很低（一般在230 mV的TPS76850 1输出电流），是成正比的输出电流。此外，由于PMOS管导通元件是电压驱动型器件，静态电流非常低，独立的输出负载（通常为85µ以上的输出电流0毫安到1全系列）。这两个关键技术规范对电池供电系统的运行寿命有了显著的改善。该LDO的家庭还具有睡眠模式；采用了TTL高信号EN（使能）调节器关闭，降低静态电流小于1µ在TJ = 25°C.
电源良好（PG）是一个积极的高输出，可用于实现上电复位或低电量指示灯。
