LA1117
1.0A Low Dropout Positive Regulators
General Description
The LA1117 is a low dropout three terminal regulator that features a low quiescent current, low input, output
and dropout voltages, as well as over temperature shutdown. The output voltage of the LA1117 is set at the
factory and trimmed to ±1%. The LA1117 is stable with a ceramic output capacitor of 4.7uF.
This family of regulators can provide either a stand-alone power supply solution or act as a post regulator for
switch mode power supplies. They are particularly well suited for applications requiring low input and output
voltage.
Features
• Min. 1.1A Output Current Limiter
• 1.4V Maximum Full load Dropout Voltage
• 3-Terminal Adjustable or Fixed , 1.5V, 1.8V, 2.5V, 3.3V and 5V Output Voltage
• Fast Load Transient Response
• Built-in Over Current Protection
• Built-in Over Temperature Protection
• Good Noise Rejection Capability
• Stable with Ceramic Cap of 4.7uF
• Package : SOT223-3L, SOT89-3L, TO252-2L
• RoHS Compliant & Halogen Free
Applications
• PC Mother Board Applications
• LCD TV/ Monitors
• Communication Devices

Note 3 : Line and load regulation are measured by low duty cycle pulse testing and the junction temperature is kept at 25 degree C. The
VOUT of load regulation is measured at the out lead.
Note 4 : Guarantee by design. Not 100% tested in manufacturing.
