RH117
Positive
Adjustable Regulator
The RH117 is a 3-terminal positive adjustable regulator
capable of supplying up to 0.5A (H package) or 1.5A
(K package). The output is adjusted using two external
resistors for a range of 1.2V to 37V. The devices have full
current limit thermal overload safe area protection, all of
which remain functional even if the adjustment terminal is
disconnected.
The wafer lots are processed to LTC’s in-house Class S
flow to yield circuits usable in stringent military applications. In addition to 883 processing, the RH117 is subjected to 100% burn-in in thermal limit.

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.
