MAXIM MAX6023 Technical data

General Description

The MAX6023 is a family of low-dropout, micropower
voltage references in a 5-bump, chip-scale package
(UCSP™). The MAX6023 series-mode (three-terminal)
references, which operate with input voltages from 2.5V
to 12.6V (1.25V and 2.048V options) or (V

OUT

+ 0.2V) to

12.6V (all other voltage options), are available with out­put voltage options of 1.25V, 2.048V, 2.5V, 3.0V,

4.096V, 4.5V, and 5.0V. These devices are guaranteed
an initial accuracy of ±0.2% and 30ppm/°C tempera­ture drift over the -40°C to +85°C extended temperature
range.

UCSPs offer 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 makes the device ideal for
height-critical applications. Miniature UCSP packages
also enable device placement close to sources and
allow more flexibility in a complex or large design layout.

The MAX6023 voltage references use only 27µA of sup­ply current. And unlike shunt-mode (two-terminal) refer­ences, the supply current of the MAX6023 family varies
only 0.8µA/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 2.2nF of load capaci­tance. The low-dropout voltage and the low supply cur­rent make these devices ideal for battery-operated
systems.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

Note 1: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device

can be exposed to during board-level solder attach and rework. This limit permits only the use of solder profiles recom­mended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and convection reflow.
Preheating is required. Hand or wave soldering is not allowed.
