APPLICATIO S
3.3V to 2.5V Logic Power Supplies
Post Regulator for Switching Supplies
The LT
®
1963 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
LT1963 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 LT1963
regulators are stable with output capacitors as low as
10µF. 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
LT1963 regulators are available in 5-lead TO-220, DD,
3-lead SOT-223, 8-lead SO, and Exposed Pad 16-lead
TSSOP packages.
