DESCRIPTION
The Aeroflex Plainview VRG8651/8652 consists of one Positive Adjustable (RH1086) and one Negative Adjustable
(RH1185) LDO voltage regulator capable of supplying 1.0Amps (RH1086) /3Amps(RH1185) respectively over the
output voltage range as defined under recommended operating conditions. The VRG8651/8652 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 VRG8651/8652 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 VRG8651/8652 has been specifically designed to meet exposure to radiation environments. The VRG8651 is
configured for a Thru-Hole 8 lead metal power package and the VRG8652 is configured for a Surface Mount 8 lead
metal power package. It is guaranteed operational from -55°C to +125°C. Available screened to MIL-STD-883, the
VRG8651/8652 is ideal for demanding military and space applications.

Notes
1. Meets ESD testing per MIL-STD-883, method 3015, Class 2.
2. Unless otherwise specified, these specifications apply for post radiation and -55°C < Tc < +125°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. Dropout voltage is tested by reducing input voltage until the output drops 1% below its nominal value. Tests are done at 0.5A and 3A. The
power transistor looks basically like a pure resistance in this range so that minimum differential at any intermediate current can be
calculated by interpolation; V
DROPOUT
= 0.25V + (0.25Ω x I
OUT
). For load current less than 0.5A, see Figure 4.
7. “Minimum input voltage” is limited by base emitter voltage drive of the power transistor section, not saturation as measured in Note 6. For
output voltages below 4V, “minimum input voltage” specification may limit dropout voltage before transistor saturation limitation.
8. Supply current is measured on the ground pin, and does not include load current, R
LIM
, or output divider current.
9. The 25W power level is guaranteed for an input-output voltage of 8.3V to 17V. At lower voltages the 3A limit applies, and at higher
voltages the internal power limiting may restrict regulator power below 25W.
10. Line and load regulation are measured on a pulse basis with a pulse width of 2ms, to minimize heating. DC regulation will be affected by
thermal regulation and temperature coefficient of the reference.
11. V
SAT
is the maximum specified dropout voltage; 0.25V +(0.25Ω x I
OUT
).
12. Current limit is programmed with a resistor from REF pin to GND pin. R
LIM
= 15KΩ/I
LIM
.
13. 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
