DESCRIPTIO
ABSOLUTE
The RH137 negative adjustable regulator will deliver up to
1.5A output current over an output voltage range of –1.2V
to –32V.
Power Dissipation ............................... Internally Limited
Input-to-Output Voltage Differential ......................... 40V
Operating Junction
Temperature Range ......................... – 55°C to 150°C
Storage Temperature Range ................. – 65°C to 150°C
Lead Temperature (Soldering, 10 sec).................. 300°C
Every effort has been made to make these devices easy to
use and difficult to damage. Internal current and power
limiting coupled with true thermal limiting prevents device
damage due to overloads or shorts, even if the regulator is
not fastened to a heat sink.

Maximum reliability is attained with Linear Technology’s
advanced processing techniques combined with a 100%
burn-in in the thermal limit mode. This assures that all
device protection circuits are working and eliminates field
failures experienced with other regulators that receive
only standard electrical testing.
The wafer lots are processed to Linear Technology’s inhouse Class S flow to yield circuits usable in stringent
military applications.

Note 1: Unless otherwise specified, these specifications apply for
VIN – VOUT= 5V; and IOUT = 0.1A for the H package (TO-39) and
IOUT = 0.5A for the K package (TO-3) package. Although power dissipation
is internally limited, these specifications are applicable for power
dissipations of 2W for the TO-39 and 20W for the TO-3. IMAX is 0.2A for
the TO-39 and 1.5A for the TO-3 package.
Note 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.
Note 3: Guaranteed by design, characterization or correlation to other
tested parameters.
Note 4: TJ = 25°C unless otherwise noted.

PDA Test Notes
The PDA is specified as 5% based on failures from group A, subgroup 1,
tests after cooldown as the final electrical test in accordance with method
5004 of MIL-STD-883 Class B. The verified failures of group A, subgroup
1, after burn-in divided by the total number of devices submitted for burnin in that lot shall be used to determine the percent for the lot.
Linear Technology Corporation reserves the right to test to tighter limits
than those given.
