Abstract
A switching regulator circuit produces a varying reference voltage with temperature and includes at least one band-gap generator for supplying a power stage through an error amplifier and a comparator. The error amplifier is also supplied a regulated voltage which may be produced by the regulator itself. The at least one band-gap generator includes a plurality of band-gap generators being supplied by the regulated voltage and input a fraction of the regulated voltage through a voltage divider. The respective outputs of the band-gap generators are connected to a logic network which has an output connected to the power stage. The error amplifier and comparator may be included within each respective band-gap generator.
