DESCRIPTION

The Aeroflex Plainview 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).
