Available in Three Hermetic Package Styles
Radiation Tolerant up to 30 k Rad (Si)
Reference Voltage Set Internally to 鹵2%
Built-In Thermal Overload Protection
Short Circuit Current Limiting
Product Is Available Screened To Class B and Class S, MIL-STD-883
DESCRIPTION
These three terminal negative 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, they can deliver over 3.0 amps of output current. These units feature 2%
initial voltage tolerance, with 1.0% load regulation and .015% line regulation. 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.
