Change in Vo due to heating effects must be taken into account separately. Pulse testing with low duty is used. TYPICAL APPLICATION (PROGRAMMABLE REGULATOR) Ci is required when regulator is located an appreciable distance from power supply filter. Co is not needed for stability, however, in the range of 1 ㎌ to 100㎌ of aluminum or tantalum electrolytic are commonly used to provide improved output impedance and rejection of transients. Since IAdj is controlled to less then 100㎂, the error associated with this term is negligible in most applications. |
