Texas Instruments offer a range of linear voltage regulators which include LM78, LM78L and the LM78M Series that are intended for fixed voltage regulation. The three terminal positive regulators have current outputs more than 1A (LM78xx), 100 mA (LM78Lxx) and 500 mA (LM78Mxx). There is no need for external components although it is possible to adjust the voltage and current with external devices. The voltage regulators combine thermal shutdown, internal current limiting and output transistor safe-area compensation all in its own package.

Texas Instruments (TI) positive linear regulators cover a wide range of functions and tend to be used in the electronic industry. Applications include local on-card regulation, power supplies and power distribution systems.

Output current 1A: LM78xx Series
Output current 0.1A: LM78Lxx Series
Output current 0.5A: LM78Mxx Series
Range of fixed voltages
No external components required
Internal thermal overload/ Short circuit current limit protection
Output transistor safe area protection

The Texas Instruments LM78L series of three terminal positive regulator available with several fixed output voltages, making them useful in a wide range of applications. Used as a Zener-diode and resistor combination replacement, It 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 it to be used in logic systems, instrumentation, HiFi, and other solid-state electronic equipment.
