TPS75425 单输出 LDO、2.0A、固定电压 (2.5V)、电源良好 (PG) 输出、快速瞬态响应

TPS75425 描述

The TPS752xxQ and TPS754xxQ devices are low-dropout regulators with integrated power-on reset and power-good (PG) functions respectively. These devices are capable of supplying 2 A of output current with a dropout of 210 mV (TPS75233Q, TPS75433Q). Quiescent current is 75 uA at full load and drops down to 1 uA when the device is disabled. These devices are designed to have fast transient response for larger load current changes. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 210 mV at an output current of 2 A for the TPS75x33Q) 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 75 uA over the full range of output current, 1 mA to 2 A).
