UPC1943T-E2-A

Overview

The UPC1943T-E2-A is a shunt precision voltage reference manufactured by Renesas Electronics. It operates within an input voltage range of 1.26 V to 24 V and provides a stable reference output. The device features an initial accuracy of 2.4% and supports a maximum shunt current of 30 mA. Designed for surface-mount applications, it utilizes the SOT-89-3 package. The component functions reliably across a temperature range from -30°C to +85°C.

Feature Summary

• Provides precise shunt regulation for stable voltage references
• Supports wide input voltage operation up to 24 V
• Designed for surface-mount installation in compact layouts

Applications

• Precision voltage reference circuits
• Analog-to-digital converter (ADC) reference sources
• Power supply monitoring systems

Procurement Notes

Verify the specific suffix E2-A against official datasheets to confirm RoHS compliance and lead-free status. Confirm the SOT-89-3 package type matches design requirements. Ensure operating conditions remain within the specified -30°C to +85°C range and that shunt current does not exceed 30 mA during implementation.

Selection Notes

Select this component when a low-cost, high-accuracy shunt reference is required for space-constrained designs. The SOT-89-3 package offers a compact footprint suitable for dense PCB layouts. Consider the 2.4% initial accuracy and 30 mA current limit when designing series resistors and load conditions for the target application.
