    Products Detail

    The SG137A family of negative adjustable regulators delivers up to 500mA output current over an output voltage range of -1.2V to -37V. The device includes significant improvements such as better line and load regulation, with a maximum output voltage error of 1%. The SG137 family uses the same chip design with ±2% maximum output voltage error. These devices feature internal current and power limiting with true thermal limiting to prevent damage from overloads or shorts, even without a heat sink.

    Key Features

    • 1% Output Voltage Tolerance
    • 0.01%/V Line Regulation
    • 0.5% Load Regulation
    • 0.02%/W Thermal Regulation
    • High Reliability Features - Available to MIL-STD-883, MSC-AMS Level 'S' Processing Available, Available to DSCC
    • SGR137A/SGR137 Rad-Tolerant Version Available
    • Internal current and power limiting with true thermal limiting
