n 5-Lead TO-220, DD, 3-Lead SOT-223 and 8-Lead SO Packages The LT ®1963A series are low dropout regulators optimized
for fast transient response. The devices are capable of
supplying 1.5A of output current with a dropout voltage of
340mV. Operating quiescent current is 1mA, dropping to
< 1µA in shutdown. Quiescent current is well controlled; it
does not rise in dropout as it does with many other regulators. In addition to fast transient response, the LT1963A …
