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
μ
A at full load and drops down to 1
μ
A when the device
is disabled. TPS752xxQ and TPS754xxQ are designed to have fast transient response for larger load current
changes.
