Part Description

The LM78Lxx series 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 AN-1112 DSBGA Wafer Level Chip Scale Package (SNVA009) for DSBGA Considerations. For more information on the TO-92 package, see TO-92 Packing Options / Ordering Instructions (SNOA072).
