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. Absolute Maximum Ratings (Exceeding maximum ratings may damage the device.

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.
