Overview
The ZRT025GC1TC is a monolithic integrated circuit providing a precise stable reference voltage of 2.5V at an operating current of 500µA. It features a knee current of 150µA and operates within the -40°C to +85°C temperature range. The device offers 1% initial voltage tolerance, with output voltage ranging from 2.475V to 2.525V. It includes a trim facility for adjusting the output voltage over a ±5% range using a 100kΩ resistor. The component utilizes a SOT-223 package.
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 source setting
- Voltage regulation circuits
Procurement Notes
Verify that the ordering suffix TC corresponds to the C grade (-40 to 85°C) and 1% tolerance variant as documented in official Diodes Incorporated or Zetex datasheets. Confirm the package type is SOT-223 and check for specific reel quantities if applicable. Ensure compatibility with system requirements regarding the trim pin configuration when not in use.
Selection Notes
Select this component when a low-power, precision 2.5V reference is needed with high temperature stability. The 1% tolerance version suits applications requiring tighter initial accuracy than the 2% variant. Consider the trim facility if system-level calibration is necessary to compensate for errors. Verify that the operating current range of 150µA to 75mA fits the design constraints.
Part Context
The ZRT025 series consists of low power precision reference sources available in A grade (-55 to 125°C) and C grade (-40 to 85°C) variants. These devices are designed for surface mount applications and offer adjustable output voltages. The series includes both 1% and 2% initial voltage tolerance options, all housed in SOT-223 packages.
Replacement Considerations
Public confirmed substitute part numbers: ZRT025GC1TA (same grade/tolerance, different tape/reel quantity).
FAQ
How should the trim pin be handled if trimming is not required?
When the trim facility is not used, the pin should be left open circuit.
What is the maximum reverse current allowed for the ZRT025?
The maximum reverse current is 75 mA. Above 72°C, this figure should be linearly derated to 25 mA at 125°C.
