Electrically Similar To Industry Standard LM117AHV
Adjustable Output Voltage
Built In Thermal Overload Protection
Short Circuit Current Limiting
Available In Four Hermetic Package Styles
Maximum Output Voltage Tolerance Is Guaranteed to + 1%
Radiation Tolerant up to 150 K Rad (Si)
Available Hi-Rel Screened, Class B and Class S, MIL-STD-883
DESCRIPTION
These three terminal positive regulators are supplied in high density hermetically sealed
packages and available Hi-Rel screened. All protective features are designed into the circuit,
including thermal shutdown, current-limiting, and safe-area control. With heat sinking, these
devices can deliver up to 1.5 amps of output current. These units also feature output voltages
that can be fixed from 1.2 volts to 57 volts using external resistors. These devices are ideally
suited for Space applications where small size, high reliability, and radiation tolerance is
required. The high level of Radiation Tolerance of these devices makes them a desirable
choice for LEO and many MEO and GEO communication satellites. Radiation testing is
performed on a single wafer by wafer basis. Random die samples per wafer are selected,
packaged and radiation tested to qualify each individual semiconductor wafer-by-wafer.
