德州仪器的单输出 LDO、2A、固定电压 (3.3V)、SVS、快速瞬态响应芯片 TPS75233QPWP
Fast-Transient-Response 2-A Low-Dropout Voltage Regulators
德州仪器的线性稳压器IC TPS75233QPWP的说明
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 μA at full load and drops down to 1 μA 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 μA over the full range of output current, 1 mA to 2 A).
