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.

Stable with Ceramic Capacitors*

Reverse Battery Protection

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.
