Overview
The ZRT040GC1TA is a monolithic integrated circuit providing a precise stable reference voltage of 4.01V at 500μA. It features a knee current of 150μA and operates over a temperature range of -40 to +85°C. The device offers a trim facility for adjusting the output voltage within a ±5% range, with an initial voltage tolerance of 1%. Electrical characteristics include a maximum output noise figure of 50µV peak-to-peak (0.1 to 10Hz), a slope resistance of 3.0Ω, and a maximum operating current of 75mA.
Feature Summary
- Trimmable output voltage capability
- Excellent temperature stability
- Low output noise figure
- No external stabilizing capacitor required in most cases
Applications
- System error compensation
- Precision reference setting
- Surface mount applications
Procurement Notes
Verify component authenticity through authorized channels. Confirm package type matches SOT223 specifications. Ensure compliance with RoHS directives. Check for life support restrictions before deployment. Validate ordering suffixes against manufacturer documentation.
Selection Notes
Consider the trim facility when system accuracy requires adjustment beyond the standard 1% tolerance. Evaluate thermal management requirements given the 2W power dissipation rating. Assess operating current needs against the specified 150μA minimum and 75mA maximum limits. Verify compatibility with surface mount assembly processes.
Part Context
