LT1963A Series

1.5A, Low Noise,

Fast Transient Response

LDO Regulators

FeaTures

DescripTion

The

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.
