DESCRIPTION

The Aeroflex Plainview VRG8662 consists of a Positive Adjustable (RH1086) LDO voltage regulator capable of

supplying 1.0Amps over the output voltage range as defined under recommended operating conditions. The VRG8662

offers excellent line and load regulation specifications and ripple rejection. Dropout (VIN - VOUT) decreases at lower

load currents.

The VRG8662 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 VRG8662 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 VRG8662 is ideal for demanding military and space applications.

Notes:

1/ For compliance with MIL-STD- 883 revision C current density specification, the RH1086MK is derated to 1 Amp but is capable of 1.5 Amps.

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

3/ Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the input/output

differential voltage and the output current. Guaranteed maximum power dissipation will not be available over the full input/output voltage range.

4/ Dropout voltage is specified over the full output current range of the device.

5/ Not tested. Shall be guaranteed by design, characterization, or correlation to other tested parameters.

6/ Pulsed @ <10% duty cycle @+25°C for characterization only. (See note 1)
