L78M00 SERIES POSITIVE VOLTAGE REGULATORS s s 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 s s s 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 IO PD Tstg Top DC Input Voltage Output Current Power Dissipation Storage Temperature Range Operating Junction Temperature Range Parameter (for VO= 5 to 18V) (for VO= 20, 24V) Value 35 40 Internally Limited Internally Limited -65 to +150 0 to +150 Unit V V mA mW °C °C Absolute Maximum Ratings are those values beyond which damage to the device may occur.
