L78M00 SERIES POSITIVE VOLTAGE REGULATORS ■ OUTPUT CURRENT TO 0.5A ■ OUTPUT VOLTAGES OF 5; 6; 8; 9; 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 deliver over 0.5A output current. Although designed primarily as fixed voltage regulators, these devices can be DPAK IPAK used with external components adjustable voltage and currents. to obtain SCHEMATIC DIAGRAM January 2004 1/21 L78M00 SERIES ABSOLUTE MAXIMUM RATINGS Symbol VI Parameter DC Input Voltage Value Unit 35 40 V V (for VO= 5 to 18V) (for VO= 20, 24V) IO Output Current Internally Limited mA Internally Limited mW -65 to +150 °C 0 to +150 °C PD Power Dissipation Tstg Storage Temperature Range Top Operating Junction Temperature Range Absolute Maximum Ratings are those values beyond which damage to the device may occur.
