This series of fixed negative-voltage integrated-circuit voltage regulators is designed for a wide range of applications. These include on-card regulation for elimination of noise and distribution problems associatedwith single-point regulation. In addition,

ON UT UT they can be used to control series pass elements to make high-current voltage-regulator circuits. One of these regulators can deliver up to 100 m A of output current. The internal current-limiting and thermal-shutdown features make them essentially immune to overload. When used as a replacement for a zener-diode and resistor bination, these devices can provide ef fective improvement in output impedance of two orders of magnitude, with current. lower bias electrical characteristics otherwise noted) at specified virtual junction temperature,
