Product overview
The VRG8658 is a dual positive LDO adjustable voltage regulator for local power regulation in aerospace and space electronics. External components set the output voltage, allowing the regulator to match the required power rail. The two regulators are electrically isolated from one another and from the package. Thermal shutdown supports protection under excessive temperature conditions. The datasheet defines the output range, input headroom and loading conditions needed to establish a working design. Package and screening options support different assembly and procurement requirements. Select the complete ordering number to identify the applicable lead configuration, test flow and radiation assurance. Application circuits and electrical-characteristic tables provide the detail needed to set the output and evaluate thermal performance.
