TPS76801 单输出 LDO、1.0A、可调节电压（1.5 至 5.5V）、低静态电流、快速瞬态响应
TPS76801 描述
This device is designed to have a fast transient response and be stable with 10 uF capacitors. This combination provides high performance at a reasonable cost.
Since 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, because the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85 uA 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 shutdown mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to less than 1 uA at TJ = 25°C
