description
The TPS753xxQ and TPS751xxQ are low dropout regulators with integrated power-on reset and power-good
(PG) functions respectively. These devices are capable of supplying 1.5 A of output current with a dropout of
160 mV (TPS75133Q, TPS75333Q). Quiescent current is 75
碌A
at full load and drops down to 1
碌A
when the
device is disabled. TPS751xxQ and TPS753xxQ are designed to have fast transient response for larger load
current changes.
