MAX629 General Description The MAX629 micropower, low-dropout bandgap voltage reference combines ultra-low supply current and low drift in a miniature 5-pin SOT23 surface-mount package that uses 7% less board space than comparable devices in an SO package. An initial accuracy of.15% and a 3ppm/ C (max) temperature coefficient make the MAX629 suitable for precision applications. This series-mode voltage reference sources up to 4mA and sinks up to 1mA of load current. A wide 2.5V to 12.6V supply range, ultra-low 5.25µA (max) supply current, and a low 2mV dropout voltage make these devices ideal for battery-operated systems. Additionally, an internal compensation capacitor eliminates the need for an external compensation capacitor and ensures stability with load capacitances up to 1µF. The MAX629 provides six output voltages of 2.48V, 2.5V, 3V, 3.3V, 4.96V, and 5V. The MAX629 is available in a 5-pin SOT23 or an 8-pin SO package and is specified over the extended temperature range (-4 C to +85 C).

Leave unconnected or connect to ground. 5 6 OUT Reference Output Input Bypassing The MAX629 does not require an input bypass capacitor. For improved transient performance, bypass the input to ground with a.1µf ceramic capacitor. Place the capacitor as close to IN as possible. Load Capacitance The MAX629 does not require an output capacitor for stability. The MAX629 is stable driving capacitive loads from to 1pF and.1µf to 1µF when sourcing current and from to.4µf when sinking current. In applications where the load or the supply can experience step changes, an output capacitor reduces the amount of overshoot (undershoot) and improves the circuit s transient response. Many applications do not require an external capacitor, and the MAX629 offers a significant advantage in applications where board space is critical. Supply Current The quiescent supply current of the series-mode MAX629 is very small, 5.25µA (max), and is very stable against changes in the supply voltage with only 1.5µA/V (max) variation with supply voltage. The MAX629 family draws load current from the input voltage source only when required, so supply current is not wasted and efficiency is maximized at all input voltages. This improved efficiency reduces power dissipation and extends battery life. Output Thermal Hysteresis Output thermal hysteresis is the change of the output voltage at T A = +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 device. Temperature Coefficient vs. Operating Temperature Range for a 1LSB 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 (T MAX - T MIN ) with the converter resolution as a parameter. The graph assumes the reference-voltage temperature 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. Turn-On Time These devices turn on and settle to within.1% of their final value in less than 1ms. The turn-on time increases when heavily loaded and operating close to dropout. 1, 1 TEMPERATURE COEFFICIENT (ppm/ C) 1 8-BIT 1 1-BIT 12-BIT 1 14-BIT.1 16-BIT 18-BIT.1 2-BIT 1 1 1 OPERATING TEMPERATURE RANGE (T MAX - T MIN ) ( C) Figure 1.
