TPS77818 单输出 LDO、750mA、固定电压 (1.8V)、快速瞬态响应、电源良好 (PG) 输出
TPS77818 描述
TPS777xx and TPS778xx are designed to have a fast transient response and be stable with a 10-uF 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 260 mV at an output current of 750 mA for the TPS77x33) 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 uA over the full range of output current, 0 mA to 750 mA). 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 1 uA at TJ = 25°C
