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 -55°C to +125°C. Available screened to
MIL-STD-883, the VRG8660 is ideal for demanding military and space applications.
Dropout (VIN - VOUT) decreases at lower load currents.
