3 Description
The TPS7A4501-SP is a low-dropout (LDO) regulator
optimized for fast-transient response. The 5962-
1222402VHA can supply 750 mA of output current
with a dropout voltage of 300 mV. The
5962R1222403VXC can supply 1.5 A of output current with a dropout voltage of 320 mV. Quiescent
current is well controlled; it does not rise in dropout,
as with many other regulators. In addition to fast
transient response, the TPS7A4501-SP regulator has very-low output noise, which makes it ideal for
sensitive RF supply applications.
