DESCRIPTION The Aeroflex Plainview VRG8660 consists of a Positive Adjustable (RH117) voltage regulator capable of supplying 1.5Amps over the output voltage range as defined under recommended operating conditions. The VRG8660 offers excellent line and load regulation specifications and ripple rejection. The VRG8660 serves a wide variety of applications including High Efficiency Linear Regulators, Post Regulators for Switching Supplies, Constant Current Regulators, Battery Chargers and Microprocessor Supply. The VRG8660 has been specifically designed to meet exposure to radiation environments and is configured for a SMD-0.5 SMT power package. It is guaranteed operational from -55C to +125C. Available screened to MIL-STD-883, the VRG8660 is ideal for demanding military and space applications. Dropout (VIN - VOUT) decreases at lower load currents. 3 ADJ 1 VOUT RH117 Positive Regulator VIN 2 FIGURE 1 - BLOCK DIAGRAM / SCHEMATIC SCD8660 Rev F ABSOLUTE MAXIMUM RATINGS PARAMETER RANGE UNITS Lead temperature (soldering 10 Sec)DC 300 C Input-Output Voltage Differential 40 VDC 1.999 ESD 1/ KV Operating Junction Temperature Range -55 to +150 C Storage Temperature Range -65 to +150 C 1/ Meets ESD testing per MIL-STD-883, method 3015, Class 1C.
