Microchip Technology, Inc. 1.5A Three Terminal Adjustable Voltage Regulator Positive Adjustable +/-1% Tol SG117A

The SG117 and SG117A are 3-terminal positive adjustable voltage regulators which offer improved performance over the original 117 design. A major feature of the SG117A is a reference voltage tolerance guaranteed within ± 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. Moreover, the SG117A reference voltage is guaranteed not to exceed 2% when operating over the full load, line and power dissipation conditions. The SG117A adjustable regulators offer an improved solution for all positive voltage regulator requirements with load currents up to 1.5A. In addition to replacing many fixed regulators, the SG117/A can be used in a variety of other applications due to its ‘floating’ design as long as the input-to-output differential maximum is not exceeded, such as a current source. A higher voltage version is available the SG117AHV and SG117HV which offers input voltage up to 60V. Additional Features Adjustable Output Down to 1.25V 1% Output Voltage Tolerance 0.01%/V Line Regulation 0.3% Load Regulation Min. 1.5A Output Current Typical 80dB Ripple Rejection Available in Hermetic TO-257
