Fast Transient Response
DESCRIPTION
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 regula-
tors. 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. Internal protection circuitry includes reverse bat-
tery 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, 8-lead SO and 16-lead TSSOP packages.
