LT1963 Series

1.5A, Low Noise,

Fast Transient Response

LDO Regulators

FEATURES

DESCRIPTIO

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.

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 and 8-lead SO packages.
