3 Description
The LM78L series (LM78Lxx throughout this
document) of three terminal positive regulators is
available with several fixed output voltages, making
them useful in a wide range of applications. Used as
a Zener-diode and resistor combination replacement,
the LM78Lxx usually provides an effective output
impedance improvement of two orders of magnitude
and lower quiescent current. These regulators can
provide local, on-card regulation, eliminating
distribution problems associated with single-point
regulation. The available voltages allow the LM78Lxx
to be used in logic systems, instrumentation, HiFi,
and other solid-state electronic equipment.
The LM78Lxx is available in the plastic TO-92 (LP)
package, the SOIC (D) package, and a chip-sized
package (8-Bump DSBGA) using TI's DSBGA
package technology. With adequate heat sinking, the
regulator can deliver 100-mA output current. Current
limiting is included to limit the peak output current to
a safe value. Safe area protection for the output
transistors is provided to limit internal power
dissipation. If internal power dissipation is too high for
the heat sinking provided, the thermal shutdown
circuit prevents the IC from overheating.
See the AN-1112 DSBGA Wafer Level Chip Scale
Package application note for DSBGA considerations.
For more information on the TO-92 package, see the
TO-92 Packing Options/Ordering Instructions
application report.
