DESCRIPTION
The Aeroflex Plainview VRG8653/54 consists of one Positive Adjustable (RH1084) and one Negative Adjustable
(RH1185) LDO voltage regulator, both capable of supplying 3.0Aover the output voltage range as defined under
recommended operating conditions. The VRG8653/54 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 VRG8653/54 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 VRG8653/54 has been specifically designed to meet exposure to radiation environments and is configured for a
Thru-Hole 8 lead metal power package and the VRG8654 is configured for a Surface Mount 8 lead metal power
package. It is guaranteed operational from -55°C to +125°C. Available screened in accordance with MIL-PRF-38534,
the VRG8653/54 is ideal for demanding military and space applications.
Dropout (VIN - VOUT) decreases at lower load currents for both regulators.

Notes
1/ The manufacturer’s output current rating for the RH1084MK positive regulator integrated circuit is 5.0 Amps. For Compliance
with the Current Density specification of MIL-STD-883 Rev. C, the electrical performance characteristics are specified at an
output current of 3.0 Amps.
2/ Specification derated to reflect total dose exposure to 100krads (Si) at +25°C.
3/ Line and load regulation are guaranteed up to the maximum power dissipation of 25W. 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; VDROPOUT = 0.25V + (0.25 x IOUT). 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, RLIM, 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/ VSAT is the maximum specified dropout voltage; 0.25V +(0.25 x IOUT).
12/ Current limit is programmed with a resistor from REF pin to GND pin. RLIM = 15K/ILIM.

The maximum Power dissipation is limited by the thermal shutdown function of each regulator chip in the
VRG8653/54. The graph above represents the achievable power before the chip shuts down. The first line in the
graph represents the maximum power dissipation of the VRG8653/54 with one regulator on (the other off) and the
other line represents both regulators on dissipating equal power. If both regulators are on and one regulator is
dissipating more power that the other, the maximum power dissipation of the VRG8653/54 will fall between the two
lines. This graph is based on the maximum junction temperature of 150°C and a thermal resistance (JC) of 5°C/W.

The RH1185 output voltage is set by two external resistors.
Internal reference voltage is trimmed to
2.37V so that a standard 1% 2.37k resistor (R1) can be
used to set divider current at 1mA. R2 is then selected
