Figure 6-21 shows a MAX406 combined with a low-dropout MAX872 to form a precise -2.5-V reference that requires no external components. Typically, the MAX872 requires two external resistors. Maximum current drain is 11 μA. There is no degradation of voltage because of load regulation and no compensation is needed for load capacitance. The supplies need not have precise regulation. The positive supply can be as low as 1.1 V with the negative supply as low as 2.7 V. MAXIM NEW RELEASES DATA BOOK, 1994, P. 3-31.
