TPS75815 单输出 LDO、3.0A、固定电压 (1.5V)、快速瞬态响应、低静态电流
TPS75815 描述
The TPS758xx family of 3A low dropout (LDO) regulators contains four fixed voltage option regulators and an adjustable voltage option regulator. These devices are capable of supplying 3A of output current with a dropout of 150mV (TPS75815). Therefore, the device is capable of performing a 3.3V to 2.5V conversion.
Quiescent current is 125uA at full load and drops to less than 1uA when the device is disabled. The TPS758xx 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 very low (typically 150mV at an output current of 3A for the TPS75815) 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 125uA over the full range of output current).
