L78M00 series Positive voltage regulators Feature summary ■ Output current to 0.5A ■ Output voltages of 5; 6; 8; 9; 10; 12; 15; 18; 20; 24V ■ Thermal overload protection ■ Short circuit protection ■ Output transition SOA protection TO-220 TO-220FP Description The L78M00 series of three-terminal positive regulators is available in TO-220, TO-220FP, DPAK and IPAK packages and with 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. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can DPAK IPAK deliver over 0.5A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.
