1.5 A Negative
Voltage Regula
Description
This series of fixed-negative-voltage monolithic integrated-circuit voltage regulators is designed to complement Series MIK7800 in a
wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated
with single point regulation. Each of these regulators can deliver up to 1.5 amperes of output current. The internal current limiting and
thermal shutdown features of these regulators make them essentially immune to overload. In addition to use as fixed-voltage regulators,
these devices can be used with external components to obtain adjustable output voltages and current and also as the power pass
element in precision regulators.

When using a negative regulator, bypass capacitors are a
must on both the input and output. Recommended values are
2 µF on the input and 1 µF on the output. It is considered good
practice to include a 0.1 µF capacitor on the output to improve
the transient response (Fig. 1). These capacitors may mylar,
ceramic, or tantalum, provided that they have good high
frequency characteristics.
