DESCRIPTION
The VRG8691/92 is capable of supplying in excess of 7.5Amps over the output voltage range as defined under recommended operating conditions. The
regulator is exceptionally easy to set-up, requiring only 2 external resistors to set the output voltage. The module design has been optimized for excellent regulation and low drop-out voltage. Figures 2 through 5 illustrate setting output voltage, setting current limits and choosing a slow start capacitor. The VRG8691/92 serves a wide variety of applications including local on-card regulation, programmable output voltage regulation or precision current regulation...
