Overview
The UPC1093TA-1-E1-AT is an adjustable precision shunt voltage reference IC manufactured by Renesas Electronics. It operates within a supply voltage range of up to 36 V and provides an adjustable output voltage starting from a minimum of 2.495 V. The device features a cathode current rating of 1 mA and supports a maximum load current of 150 mA. It exhibits a temperature coefficient of 100 ppm/°C and maintains a tolerance of ±2%. Designed for surface-mount applications, it is housed in a compact SC-74A (SOT-363) package with five pins. The component functions reliably across an operating temperature range of -20°C to 85°C.
Feature Summary
- Adjustable shunt regulation architecture allowing precise voltage setting
- High input voltage capability supporting systems up to 36 V
- Compact SC-74A surface-mount packaging for space-constrained designs
Applications
- Precision voltage reference sources for analog-to-digital converters
- Battery-powered equipment requiring stable reference voltages
- Portable instrumentation and measurement devices
Procurement Notes
Verify the specific suffix E1-AT against the manufacturer's latest datasheet to confirm pinout compatibility and tape-and-reel specifications. Ensure that the SC-74A footprint matches your PCB layout requirements. Confirm RoHS compliance status and moisture sensitivity level prior to assembly to prevent handling damage during soldering processes.
Selection Notes
Select this component when an adjustable shunt regulator is required in a small form factor. The 36 V input range suits higher voltage rails, while the 150 mA load capability allows for moderate current sourcing. Consider the 100 ppm/°C temperature coefficient for applications where thermal stability is critical but ultra-low drift is not mandatory.
Part Context
This part belongs to the UPC1093 series of bipolar analog integrated circuits designed as precision shunt regulators. The series offers various package options including SOP and SC-74A. The UPC1093TA variant specifically denotes the surface-mount configuration optimized for automated assembly processes in consumer and industrial electronics.
Replacement Considerations
Check for direct substitutes such as the UPC1093G-1-E1-A or UPC1093J-A, noting differences in package type (SOIC vs SC-74A) and availability status. Verify electrical parameter equivalence before substitution.
