TPS75725 单输出 LDO、3.0A、固定电压 (2.5V)、快速瞬态响应、低静态电流
TPS75725 描述
The TPS757xx family of 3-A low dropout (LDO) regulators contains four fixed voltage option regulators with integrated power-good (PG) and an adjustable voltage option regulator. These devices are capable of supplying 3 A of output current with a dropout of 150 mV (TPS75733). Therefore, the device is capable of performing a 3.3-V to 2.5-V conversion. Quiescent current is 125 uA at full load and drops down to less than 1 uA when the device is disabled. The TPS757xx is designed to have fast transient response for large load current changes.
Because the PMOS device behaves as a low-value resistor, the dropout voltage is low (typically 150 mV at an output current of 3 A for the TPS75733) and is directly proportional to the output current
