Abstract: In described examples, in response to a first reference voltage (REF1), a regulator (104) regulates an output voltage (VOUT) of a line (102), so that the output voltage (VOUT) is approximately equal to a target voltage. In response to the output voltage (VOUT) rising above a second reference voltage (REF2), pull down circuitry (106) draws current from the line (102). In response to the output voltage (VOUT) falling below the second reference voltage (REF2) by at least a predetermined amount, the pull down circuitry (106) ceases to draw current from the line (102). The first and second reference voltages (REF1, REF2) are based upon a same band gap reference as one another.

Abstract: Circuitry to provide a supply voltage. A voltage regulator is coupled to receive a target reference signal. The voltage regulator generates a supply voltage (Vtt) and is coupled to receive the supply voltage as an input signal. An upper limit comparator receives an upper limit voltage signal that is higher than the target reference voltage signal and the supply voltage to generate a "too high" signal when the supply voltage exceeds an upper threshold. A lower limit comparator receives a lower limit voltage signal that is lower than the target reference voltage signal and the supply voltage to generate a "too low" signal when the supply voltage is below a lower threshold. A pull up current source is coupled to pull the supply voltage up in response to the too low signal. A pull down current source is coupled to pull the supply voltage down in response to the too high signal.
