Features

Description

●

Adjustable or Fixed Output

The LM1117 series of positive adjustable and fixed

regulators are designed to provide 1A with high

efficiency. All internal circuitry is designed to

operate down to 1.4V input to output differential.

The product is specifically designed to provide well-

regulated supply for low-voltage IC application such

as high-speed bus termination and low current 3.3V

logic supply, and other applications such as VGA cards.

Output Current of 1A

Low Dropout, 1.4V max at 1A Output Current

Good Noise Rejection

Output Current Limiting

Built-in Thermal Shutdown

●

Fast Transient Response

Can operate using MLCCs in the capacitance range

of 2μF to 10μF

Applications

●

High Efficiency Linear Regulators

Post Regulators for Switching Supplies

Note : 1.See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at

a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead 1/18” from the

package.

2. Line and load regulation are guaranteed up to the maximum power dissipation of 6.7W. Power dissipation is determined by the

difference in input and output and the output current. Guaranteed maximum power dissipation will not be available over the full

input/output range.
