Features
Description
Adjustable or Fixed Output
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
●
●
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 wellregulated 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.
Applications
High Efficiency Linear Regulators
● Post Regulators for Switching Supplies
● Adjustable Power Supply

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 1W. 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.
