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 regulators have very low output noise which
makes them ideal for sensitive RF supply applications.
Output voltage range is from 1.21V to 20V. The LT1963A
regulators are stable with output capacitors as low as
10μF. Small ceramic capacitors can be used without the
necessary addition of ESR as is common with other
regulators. Internal protection circuitry includes reverse
battery protection, current limiting, thermal limiting and
reverse current protection. The devices are available in
fixed output voltages of 1.5V, 1.8V, 2.5V, 3.3V and as an
adjustable device with a 1.21V reference voltage. The
LT1963A regulators are available in 5-lead TO-220, DD,
3-lead SOT-223 and 8-lead SO packages.
