Description
The CR160 series is a family of
regulators designed for demanding applications in test
equipment and instrumentation. These devices combine
a JFET with an integrated resistor to produce a single
two-leaded device which is extremely simple to operate.
With nominal current ranges from 1.60 mA to 4.70 mA,
10% range current
this series will meet a wide array of design requirements.
The TO-206AA hermetically sealed package is available
with military processing per MIL-S-19500 (see Military
Information).
