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). 1 VIN 2 3 VBIAS 4 VRG8691/92 12 11 VOUT 10 9 VSENSE ENABLE GND 5 6 8 Current Limit 7 Slow Start SCD8691 Rev J FIGURE 1 – BLOCK DIAGRAM / SCHEMATIC 1 Cobham Semiconductor Solutions www.cobham.com/HiRel ABSOLUTE MAXIMUM RATINGS PARAMETER Operating (Junction) Temperature Range Lead Temperature (soldering, 10 sec) Storage Temperature Range VBIAS, VIN Thermal Resistance (Junction to case JC) Power RANGE -55 to +150 300 -65 to +150 7 1 25 1/ UNITS °C °C °C V °C/W W 1/ Based on pass transistor limitations of (VIN - VO) x IO and JC < 1°C/W with 25°C max TJ rise and TC = +125°C.
