L79xxC
Negative voltage regulators
Features
■ Output current up to 1.5 A
■ Output voltages of -5; -8; -12; -15; -20 V
■ Thermal overload protection
■ Short circuit protection
■ Output transition SOA protection
Description
The L79XXC series of three-terminal negative
regulators is available in TO-220, TO-220FP and
D2PAK packages and several fixed output
voltages, making it useful in a wide range of
applications. These regulators can provide local
on-card regulation, eliminating the distribution
problems associated with single point regulation;
furthermore, having the same voltage option as
the L78XX positive standard series, they are
particularly suited for split power supplies. If
adequate heat sinking is provided, they can
deliver over 1.5 A output current.
Although designed primarily as fixed voltage
regulators, these devices can be used with
external components to obtain adjustable
voltages and currents.
