LT1963A Series

1.5A, Low Noise,

Fast Transient Response

LDO Regulators

FEATURES

DESCRIPTIO

The LT^®1963A series are low dropout regulators opti-

mized 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<1mAinshutdown. Quiescentcurrentiswellcontrolled;

it does not rise in dropout as it does with many other

regulators. 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

■

Output Current: 1.5A

■

Dropout Voltage: 340mV

■

Low Noise: 40mV_RMS(10Hz to 100kHz)

■

1mA Quiescent Current

No Protection Diodes Needed

Controlled Quiescent Current in Dropout

Fixed Output Voltages: 1.5V, 1.8V, 2.5V, 3.3V

Adjustable Output from 1.21V to 20V

<1mA Quiescent Current in Shutdown

Stable with 10mF Output Capacitor

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

10mF. Small ceramic capacitors can be used without the

necessary addition of ESR as is common with other

regulators. 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

LT1963A regulators are available in 5-lead TO-220, DD,

3-lead SOT-223 and 8-lead SO packages.
