Bypassing/Output Capacitance For the best line-transient performance, decouple the input with a 0.1μF ceramic capacitor as shown in the Typical Operating Circuit. Place the capacitor as close to IN as possible. When transient performance is less important, no capacitor is necessary. The MAX6043 does not require an output capacitor for stability and is stable with capacitive loads up to 100μF. In applications where the load or the supply can experi - ence step changes, a larger output capacitor reduces the amount of overshoot (undershoot) and improves the circuit’s transient response. Place output capacitors as close to the device as possible for best performance. Supply Current The MAX6043 consumes 320μA of quiescent supply current. This improved efficiency reduces power dissipa - tion and extends battery life. Thermal Hysteresis Thermal hysteresis is the change in the output voltage at TA = +25°C before and after the device is cycled over its entire operating temperature range. Hysteresis is caused by differential package stress appearing across the band- gap core transistors. The typical thermal hysteresis value is 150ppm. Turn-On Time The MAX6043 typically turns on and settles to within 0.05% of the preset output voltage in 150μs. Short-Circuited Outputs The MAX6043 features a short-circuit-protected output. Internal circuitry limits the output current to 60mA when short-circuiting the output. Temperature Coefficient vs. Operating Temperature Range for a 1 LSB Maximum Error In a data converter application, the reference voltage of the converter must stay within a certain limit to keep the error in the data converter smaller than the resolution limit through the operating temperature range. Figure 1 shows the maximum allowable reference-voltage temperature coefficient to keep the conversion error to less than 1 LSB, as a function of the operating temperature range MAX - TMIN) with the converter resolution as a param- eter. The graph assumes the reference-voltage tempera- ture coefficient as the only parameter affecting accuracy. In reality, the absolute static accuracy of a data converter is dependent on the combination of many parameters such as integral nonlinearity, differential nonlinearity, offset error, gain error, as well as voltage-reference changes.
