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.

Notes:

1/ Specification derated to reflect Total Dose exposure to 100Krad (Si) @ +25°C.

2/ Regulation is measured at a constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating

effects are covered under the specification for thermal regulation. Measurements taken at the output lead must be adjusted for lead resistance.

3/ Not tested. Shall be guaranteed to the specified limits.

4/ Pulsed at <10% duty cycle @ 25°C.

5/ Testing over 12 watts is not performed over + 25°C.

The maximum Power dissipation is limited by the thermal shutdown function of the regulator chip in the VRG8660.

The graph above represents the achievable power before the chip shuts down. The line in the graph represents the

maximum power dissipation of the VRG8660 This graph is based on the maximum junction temperature of 150°C

and a thermal resistance (JC) of 3°C/W.
