Precision adjustable shunt voltage reference
Description
The ACE432 series ICs are low voltage three-terminal adjustable regulators with guaranteed thermal
stability over a full operation range. These ICs feature sharp turn-on characteristics, low temperature
coefficient and low output impedance, which make them ideal substitutes for Zener diodes in applications
such as switching power supply, charger, motherboard and other adjustable regulators.
The output voltage can be set to any value between 1.24V and 18V with two external resistors.
The ACE432 precision reference is offered in two voltage tolerance: 0.5% and 1.0%.
These ICs are available SOT-23-3.

Note 1: Stresses greater than 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 under “Recommended Operating Conditions” is not implied. Exposure to “Absolute Maximum Ratings” for
extended periods may affect device reliability.
