AP117/AP117A
Rad-Hard Adjustable Positive Linear Voltage Regulator
Features
Rad-Hard to 300 krad TID 1
Single Event, latch-up immune (LET= 87 MeV/mg/cm2)
Wide Input/Output Voltage Differential: 40V
K-level screening
Excellent Temperature Stability
The AP117/117A are space qualified, wide-input range positive linear voltage regulators designed for military and space
flight applications. Packaged in a hermetic tabless TO-257 package, the AP117/117A provides up to 1.5A of output
current over the full input voltage range of 2.5V to 40V. The device also features internal thermal shutdown, output
current-limiting circuitry and up to ±1% initial output accuracy. The AP117/117A is an excellent choice for applications
requiring high radiation tolerance, low noise and high power supply rejection ratios.
These voltage regulators are provided in adjustable output voltage configurations only. Consult the factory for fixed
output versions. The adjustable version requires only 2 external resistors to program the output from 1.25V to 37V.

Notes:
1. At the time of publication of this datasheet, API Technologies/Marlborough did not have a DLA
certified radiation hardness assurance program.
2. 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.
3. TID Radiation Testing is performed per MIL-STD-883, Method 1019.
4. Internal SOA Protection Limits Output Current With High Input Voltage.
5. Vin 9V and COUT 44 uF
6. VDIFF 39V @ 125oC
7. At 125oC, a 1.5A output requires an I/O differential of 6.75 V.
