Rad-Hard, Negative Voltage Regulator

APNREG Series
Rad-Hard Temperature Stable Negative Voltage Regulators/References
Adjustable and Fixed Temperature Stable Regulators and References Manufactured in a Certified Class-K Facility
Features
• Rad-Hard to 300 krad TID (note 1)
• Single Event Latch-up (SEL) immune (LET>87 MeV/mg/cm2)
• Wide Input/Output Voltage Differential: 40V
• K-level screening
• Excellent Temperature Stability
The APNREG Series are space qualified, wide-input range negative linear voltage regulators designed for military and
space flight applications. Packaged in a hermetic TO-257 package, the regulators provide up to 1.5A of output current
over their full input voltage range as per specification (see table 1). The device also features internal thermal shutdown
and output current-limiting circuitry. This series is an excellent choice for applications requiring high radiation tolerance,
low noise and high power supply rejection ratios.
These voltage regulators are provided in both adjustable and fixed output voltage configurations. The adjustable version
requires only one external resistor to program the output.

At the time of publication of this datasheet, API Technologies/Marlborough did not have a DLA certified radiation hardness assurance program.
Load & Line regulation are measured at constant (Tj) junction temperature using a low duty cycle pulse. Changes in output voltage due to heating effects must
be evaluated separately.
TID radiation testing is performed per MIL-STD-883, method 1019.
Internal SOA protection limits output current with high input voltage.
Minimum exposure where parameters are guaranteed to stay within spec.
Vin ≤ -9V and COUT ≥ 44 uF
VDIFF ≥ 39V @ 125oC
At 125oC, a 1.5A output requires an I/O differential of ≥ 6.75 V.
Please see Table 1 for values and limits of the various versions.

Notes:
1. Protection resistor is 10 Ohms and is internally connected between the Output pin and the Sense pin to prevent a high
Output Voltage excursion should the external remote sense connection be severed.
2. For fixed output versions, output tolerance is adjustable to zero with one external resistor.
3. Both Output Accuracy and Temperature Drift are specified as ± 25 mV Max. However, the sum of the two will not
exceed +/- 25 mV (Applies to the non-TC versions only).
