RH117
Positive
Adjustable Regulator
DESCRIPTIO
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 applica-
tions. In addition to 883 processing, the RH117 is sub-
jected to 100% burn-in in thermal limit.
