TPS767xxx: Fast-Transient-Response 1-A LDO Voltage Regulators
单通道 LDO TPS76733QDR和 TPS76733QPWP的说明
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 TPS76750) 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 1 μA at TJ = 25°C.
