The maximum steady state usable output current and input voltage are very dependent on the heat sinking and/or lead length of the package. The data above represent pulse test conditions with junction temperature as indicated at the initiation of tests. 2. Power dissipation PD 0.75W. 3. These parameters although guaranteed over the recommended operating conditions are not 100% tested in production. 4. Recommend minimum load capacitance of 0.01uF to limit high frequency noise. 5. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device outside of its stated operating conditions. * CI is required if regulator is located an appreciable distance from power supply filter. ** Co is not needed for stability; however, it does improve transient response. 2 MC78L05AB Typical Application 3(8) INPUT C1 0.33 F NOTE1 NOTE 2 KA78LXXA MC78L05AB NOTE 1 1(1) OUTPUT 0. 1 F NOTE1 NOTE 2 2(2,3,6,7) '( )' : 8SOP Type Note: 1. Bypass Capacitors are recommend for optimum stability and transient response and should be located as close as possible to the regulator 3 MC78L05AB Mechanical Dimensions Package Dimensions in millimeters TO-92 4.58 -0.15 +0.25 0.46 14.47 0.40 0.10 4.58 0.20 1.27TYP [1.27 0.20] 3.60 0.20 1.27TYP [1.27 0.20] 0.38 -0.05 +0.10 3.86MAX 1.02 0.10 0.38 -0.05 +0.10 (R2.29) 4 (0.25) MC78L05AB Mechanical Dimensions (Continued) Package Dimensions in millimeters 8-SOP MIN 1.55 0.20 0.061 0.008 0.1~0.25 0.004~0.001 #1 #8 4.92 0.20 0.194 0.008 5.13 MAX 0.202 ( #4 #5 6.00 0.30 0.236 0.012 +0.10 0.15 -0.05 +0.004 0.006 -0.002 0.56 ) 0.022 1.80 MAX 0.071 MAX0.10 MAX0.004 3.95 0.20 0.156 0.008 5.72 0.225 0.50 0.20 0.020 0.008 0~ 8 1.27 0.050 0.41 0.10 0.016 0.004 5 MC78L05AB Ordering Information Product Number MC78L05ABP MC78L05ABD Package TO-92 8-SOP Output Voltage Tolerance 5% Operating Temperature -40 ~ +125C DISCLAIMER FAIRCHILD SEMICONDUCTOR RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
