LM78XX 3-Terminal Positive voltage Regul ators DESCRIPTION These voltage regulat ors are designed as fixed-voltage regul ators for a wide variety of application s including local, on-card regulation. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtai n adjustable voltages and currents. FEA TURES ■ Output current in excess of 1 .5A ■ No external components required ■ Output Voltages (5V, 6V, 8V, 9V, 1 0V, 12V, 15V, 18V) ■ Internal Thermal shutdown and SOA protection ■ Output voltage offered in 4% Tolerance ■ Pb -Free Packages are available ■ High E SD Level (HBM>8000V, MM>800V) TYPICAL A

PPLICATION The input voltage must remain typically 2.0V above the output voltag e even during the low point on the ripp le voltage. * CI is required if regulat or is located an appreciable Distance f rom power filter. * CO improves transie nt response. Values of ≤ 0.1 µF coul d cause instability. www.apsemi.com R EV. 03 1 LM78XX Maximum Ratings (TA=2 5 °C, unless otherwise noted) Rating Symbol Value Unit TO-220F TO-220 TO -252 Input Voltage (5V – 18V) VI 35 V Power Dissipation Thermal Resista nce of Junction to Ambient Thermal Resi stance of Junction to Case Storage Temp erature Junction Temperature Operating Temperature PD RθJA RθJC TSTG TJ TOP R 22 65 65 55 -55 ~ 125 + 150 -40 ~ 12 5 1.3 92 5 W °C/W °C/W °C °C °C Stresses exceeding Maximum ratings may damage the device. Maximum ratings are stress ratings. Functional operation above the recommended operating conditi ons is not implied. Extended exposure to stresses the above the recommended o perating conditions may affect device reliability. PD(max) = (TJ(max)–TA) ÷ θJA. Exceeding the maximum allowabl e power dissipation will result in exc essive die temperature, and the regulat or will go into thermal shutdown.
