Vout = 1.25 V (1+R2/R1) + IAdjR2 Since IAdj is controlled to less than 100A, the error associated with this term is negligible in most applications. w w w .D a aS t ee h 4U t om .c 1 IL317L ELECTRICAL CHARACTERISTICS DIE ON WAFER (VI - Vo = 3.0V, IO = 40mA, TA=25C, unless otherwise noted, Imax and Pmax (Note 1) CHARACTERISTIC Reference Voltage (TA= -10C to +125C) Line Regulation (Note 2) Line Regulation (TA= -10C to +125C), (Note 2) .

Imax=100mA, Pmax=625mW; 2. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty cycle is used. Fig.1 Test Circuit for Vo>1.25V i=0,1F, o=1,0 F. Vo=1,25(1+R2/R1)IADJ R2 Fig.2 Test Circuit for Vo=1.25V i=0,1F, o=1,0 F. 2 IL317L 3 IL317L 4 |
