.. MC7800, MC7800A, NCV7805 1.0 A Positive Voltage Regulators These voltage regulators are monolithic integrated circuits designed as fixed- voltage regulators for a wide variety of applications including local, on- card regulation. These regulators employ internal current limiting, thermal shutdown, and safe- area pensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external ponents to obtain adjustable voltages and currents. - Output Current in Excess of 1.0 A - No External ponents Required - Internal Thermal Overload Protection - Internal Short Circuit Current Limiting - Output Transistor Safe- Area pensation - Output Voltage Offered in 2% and 4% Tolerance - Available in Surface Mount D2PAK- 3, DPAK- 3 and Standard 3- Lead Transistor Packages - NCV Prefix for Automotive and Other Applications Requiring Site and Control Changes - Pb- Free Packages are Available MAXIMUM RATINGS (TA = 25°C, unless otherwise noted) Value Rating Input Voltage Power Dissipation Thermal Resistance, Junction- to- Ambient Thermal Resistance, Junction- to- Case Storage Junction Temperature Range Operating Junction Temperature (5.0 - 18 V) (24 V) Symbol VI PD Rq JA Rq JC Tstg TJ 369C 221A 35 40 Internally Limited 92 5.0 65 5.0 - 65 to +150 +150 Figure 14 5.0 936 Vdc W °C/W °C/W °C °C Unit http://onsemi.
