The LT117A Series are 3-terminal positive adjustable voltage regulators which offer improved performance over earlier devices. A major feature of the LT117A is the output voltage tolerance is guaranteed at a maximum of ±1%, allowing an overall power supply tolerance to be better than 3% using inexpensive 1% resistors. Line and load regulation performance has been improved as well. Additionally, the LT117A reference voltage is guaranteed not to exceed 2% when operating over the full load, line and power dissipation conditions. The LT117A adjustable regulators offer an improved solution for all positive voltage regulator requirements with load currents up to 1.5 amps. For performance curves and applications circuits see the LT117A series data sheet.
Applications
- Wide Range Power Supplies
