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.
The VRG8691/92 has been specifically designed to meet exposure to radiation environments. The
VRG8691 is configured for a Thru-Hole 12 lead metal power package and the VRG8692 is configured for
a Surface Mount 12 lead metal power package. It is guaranteed operational from -55°C to +125°C.
Available screened to MIL-STD-883, the VRG8691/92 is ideal for demanding military and space
applications.
CURRENT LIMIT (ICL)
The VRG8691/92 features internal current limiting making them virtually blowout-proof against overloads.
The limit is nominally 11.5A @ Vin = 5V (see Table 2), but may be increased or decreased with the addition
of one external resistor (see Application Note 2).
