Introduction

The COSTLVH431 and COSTLVH432 are adjustable precision voltage references with specified thermal stability over applicable industrial and commercial temperature ranges. Output voltage can be set to any value between VREF (1.24V) and 18V with two external resistors. The COSTLVH431A, B and C series features reference accuracy of ±0.5%, ±1.0% and ±1.5%, respectively. These devices exhibit a sharp low current turn−on characteristic with a low dynamic impedance of 0.2Ω over an operating current range of 100uA to 100 mA. The combination of features makes this series an excellent replacement for zener diodes in numerous application circuits that require a precise reference voltage. The COSTLVH432 device is identical to the COSTLVH431 device, but is offered with different pinouts for the 3-pin SOT23-3/SC70-3 packages.
