LT1963A Series

1.5A, Low Noise,

Fast Transient Response

LDO Regulators

FEATURES

DESCRIPTION

TheLT^®1963Aseriesarelowdropoutregulatorsoptimized

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.

Optimized for Fast Transient Response

Reverse Battery Protection

Output voltage range is from 1.21V to 20V. The LT1963A

regulators are stable with output capacitors as low as

10μF.Internalprotectioncircuitryincludesreversebattery

protection, current limiting, thermal limiting and reverse

currentprotection.Thedevicesareavailableinﬁxedoutput

voltages of 1.5V, 1.8V, 2.5V, 3.3V and as an adjustable

devicewitha1.21Vreferencevoltage.TheLT1963Aregula-

tors are available in 5-lead TO-220, DD, 3-lead SOT-223,

8-lead SO and 16-lead TSSOP packages.
