description

The TPS752xxQ and TPS754xxQ 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. TPS752xxQ and TPS754xxQ are designed to have fast transient response for larger load current

changes.
