The extremes of these characteristics are found in MAX6023EBT12 (1.25V output) and the MAX6023EBT50 (5.0V output). The Typical Operating Characteristicsof the remainder of the MAX6023 family typically lie between these two extremes and can be estimated based on their output voltage.

Precision, Low-Power, Low-Dropout, UCSP Voltage Reference Detailed Description The MAX6023 precision bandgap references use a proprietary curvature correction circuit and laser- trimmed thin-film resistor, resulting in a low temperature coefficient of <30ppm/ °C and initial accuracy of better than 0.2%. These devices can sink and source up to 500µA with <200mV of dropout voltage, making them attractive for use in low-voltage applications. Applications Information Output/Load Capacitance The MAX6023 devices do not require an output capaci- tor for dynamically stable, oscillation-free operation. They are stable for capacitive loads from 0 to 2.2nF. However, in applications where the load or the supply can experience step changes, an output capacitor reduces the amount of overshoot (or undershoot) and improves the circuit ’s transient response. Many appli- cations do not need an external capacitor and this fam- ily offers a significant advantage in these applications when board space is critical. Supply Current The no-load supply current of these series-mode refer- ences is 35µA maximum, and is virtually independent of the supply voltage, with only a 0.8µA/V variation from the supply voltage. Unlike shunt-mode references that must draw the maximum load current at all times, the load current is drawn from the input voltage source only when required, so supply current is not wasted and effi- ciency is maximized at all input voltages. This improved efficiency can help reduce power dissipation and extend battery life. When the supply voltage is below the minimum speci- fied input voltage (as during turn-on), the devices can draw up to 200µA beyond the nominal supply current. The input voltage source must be capable of providing this current to ensure reliable turn-on. Output Voltage Hysteresis Output voltage hysteresis is the change in 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 bandgap core transistors. The typical temperature hysteresis value is 90ppm. Turn-On Time These devices typically turn on and settle within 0.1% of their final value; 30µs to 220µs depending on the device. The turn-on time can increase up to 1.5ms with the device operating at the minimum dropout voltage and the maximum load. UCSP Information For general UCSP package information and PC layout considerations, refer to the Maxim Application Note: UCSP— A Wafer-Level Chip-Scale Package. UCSP Reliability The UCSP represents a unique package that greatly reduces board space compared to other packages. The chip-scale package represents a unique packag- ing form factor that may not perform as well as a pack- aged product through traditional mechanical reliability tests. UCSP reliability is integrally linked to the user ’s assembly methods, circuit board material, and usage environment. The user should closely review these areas when considering use of a chip-scale package. Performance through operating-life test and moisture resistance remains uncompromised. The wafer-fabrica- tion process primarily determines the performance. Mechanical stress performance is a greater considera- tion for chip-scale packages. Chip-scale packages are attached through direct solder contact to the user ’s PC board, foregoing the inherent stress relief of a pack- aged product lead frame. Solder joint contact integrity must be considered. Comprehensive reliability tests have been performed and are available upon request. In conclusion, the UCSP performs reliably through envi- ronmental stresses. BUMP NAME FUNCTION A1, A3 I.C. Internally connected. Do not connect to this pin.
