3-TERMINAL 1A ADJUSTABLE VOLTAGE REGULATOR

AZ317

General Description

Features

The AZ317 is an adjustable three-terminal positive

voltage regulator with a very low dropout of 1.2V at

1A output current. Using 2 external resistors, the

AZ317 can provide an adjustable output voltage down

to 1.25V.

Typical 1% Output Voltage Tolerance

Typical 0.01%/V Line Regulation

Typical 0.2% Load Regulation

Very Low Dropout Voltage: 1.2V at 1A Output

Current

Trimmed Current Limit

On-chip Thermal Protection

The AZ317 includes a circuit of trimmed bandgap ref-

erence to assure output voltage accuracy to be within

1%. It also provides current limiting and thermal shut-

down. The current limit is trimmed to ensure specified

output current and controlled short-circuit current. The

On-chip thermal limiting provides protection against

any combination of overload and ambient temperature

that would create excessive junction temperature.

Operation Junction Temperature: 0 to 125 C

Applications

PC Motherboard

LCD Monitor

Graphic Card

DVD Player

Network Interface Card/Switch

Telecom Equipment

Printer and other Peripheral Equipment

The AZ317 is available in the standard SOT-223, TO-

220-3, TO-252-2 (1) and TO-263-3 power packages.
