1 / 7 page  SCD8657 Rev K ❑ Manufactured using Space Qualified RH1086 die ❑ Radiation performance - Total dose > 100 krad (Si) ❑ Two-Independent voltage regulators ❑ Thermal shutdown ❑ Output voltage adjustable: 1.25V to 23V ❑ Dropout voltage: 1.3V at 1.0Amp ❑ 3-Terminal ❑ Output current: 1.0Amp ❑ Voltage reference: 1.25V +2%, -3.2% ❑ Load regulation: 0.3% max ❑ Line regulation: 0.25% max ❑ Ripple rejection: >60dB ❑ Packaging – Hermetic metal - Thru-hole or Surface mount - 6 Leads, .655"L x .415"W x .200"Ht - Power package - Weight - 5 gm max ❑ Designed for aerospace and high reliability space applications DESCRIPTION The Aeroflex Plainview VRG8657/8658 consists of two Positive Adjustable (RH1086) LDO voltage regulators each capable of supplying 1.0Amps over the output voltage range as defined under recommended operating conditions. The VRG8657/8658 offers excellent line and load regulation specifications and ripple rejection. There is full electrical isolation between the regulators and each regulator to the package. The VRG8657/8658 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 VRG8657/8658 has been specifically designed to meet exposure to radiation environments. The VRG8657 is configured for a Thru-Hole 6 lead metal power package and the VRG8658 is configured for a Surface Mount 6 lead metal power package. It is guaranteed operational from -55°C to +125°C. Available screened to MIL-STD-883, the VRG8657/8658 is ideal for demanding military and space applications. Dropout (VIN - VOUT) decreases at lower load currents for both regulators.
