DESCRIPTION The VRG8666 consists of a Positive Adjustable (RH3080) ULDO voltage regulator capable of supplying 1.0 Amps over the output voltage range as defined under recommended operating conditions. The VRG8666 offers excellent line and load regulation specifications and ripple rejection. The VRG8666 serves a wide variety of applications including SCSI-2 Active Terminator, High Efficiency Linear Regulators, Post Regulators for Switching Supplies, Constant Current Regulators, Battery Chargers and Microprocessor Supply. The VRG8666 has been specifically designed to meet exposure to radiation environments and is configured for an SMD power package. It is guaranteed operational from -55°C to +125°C. Available screened to MIL-STD-883, the VRG8666 is ideal for demanding military and space applications. Dropout (VIN - VOUT) decreases at lower load currents. Input capacitance is required for load regulation. 1uF is recommended on Vin and Vcontrol. For stable operation, a 0.1uF capacitor should be placed on Vset and a low ESR capacitor on Vout. See Figure 5. For detailed performance characteristic curves, applications information and typical applications see the latest Linear Technology Corporation ® data sheets for their RH/LT3080, which is available on-line at www.linear.com. 3 SET VCONTROL RH3080 Positive Regulator 5 OUT 2 SENSE 4 IN 1 FIGURE 1 – BLOCK DIAGRAM / SCHEMATIC SCD8666 Rev M 1 Cobham Semiconductor Solutions www.cobham.com/HiRel ABSOLUTE MAXIMUM RATINGS Parameter Rating Units +40, -0.3 VDC Output Current 1.2 A Lead temperature (soldering 10 Sec) 300 °C Input Output Differential 26 VDC Output Voltage +36 VDC Input Voltage, VCONTROL (Voltages are Relative to VOUT) ESD 1/ 2,000 - 3,999 V Operating Junction Temperature Range -55 to +150 °C Storage Temperature Range -65 to +150 °C 5 °C/W Thermal Resistance (Junction to Case) JC 1/ Meets ESD testing per MIL-STD-883, method 3015, Class 2.

SCD8666 Rev M 3/31/2016 2 Cobham Semiconductor Solutions www.cobham.com/HiRel The maximum Power dissipation is limited by the thermal shutdown function of the regulator chip in the VRG8666. The graph above represents the achievable power before the chip shuts down. The line in the graph represents the maximum power dissipation of the VRG8666 This graph is based on the maximum junction temperature of 150°C and a thermal resistance (JC) of 5°C/W.
