Precision low drop-out voltage references

30 January 2002 Power Electronics / Power Management

The MAX6023 is a Maxim family of low drop-out, micropower voltage references in a 5-bump chip-scale (UCSP) package. The MAX6023 series-mode (three-terminal) references, which operate with input voltages from 2,5 V to 12,6 V (1,25 V and 2,048 V options) or (V_OUT + 0,2 V) to 12,6 V (all other voltage options), are available with output voltage options of 1,25 V, 2,048 V, 2,5 V, 3,0 V, 4,096 V, 4,5 V, and 5,0 V. These devices are guaranteed an initial accuracy of ±0,2% and 30 ppm/°C temperature drift over the -40 to +85°C extended temperature range.

UCSP package (1,0 x 1,5 x 0,3 mm) offers the benefit of moving to smaller footprint and lower profile devices, significantly smaller than even SC70 or SOT23 plastic surface-mount packages. The significantly lower profile (compared to plastic SMD packages) of the UCSP package makes the device ideal for height-critical applications.

The MAX6023 voltage references use only 27 µA of supply current. Unlike shunt-mode (two-terminal) references, the supply current of MAX6023 family varies only 0,8 µA/V with supply voltage changes, translating to longer battery life. Additionally, these internally compensated devices do not require an external compensation capacitor and are stable up to 2,2 nF of load capacitance.
