LT1027ECS8-5#TRPBF

Voltage Reference Overview

The LT1027ECS8-5#TRPBF is a precision series voltage reference from Analog Devices, featuring a fixed 5V output with ±0.1% initial accuracy and a temperature coefficient of 3ppm/°C. It operates within an input voltage range of 8V to 40V, drawing a maximum supply current of 3.5mA while delivering up to 15mA load current. The device exhibits low noise characteristics, specified at 3µVp-p (0.1Hz to 10Hz) and 10µVrms (10Hz to 10kHz). Designed for surface-mount applications, it is housed in an 8-SOIC package and functions reliably across a commercial temperature range of 0°C to +70°C.

Voltage Reference Feature Summary

• Delivers high-precision fixed voltage regulation with tight initial tolerance and minimal thermal drift.
• Provides robust load drive capability suitable for demanding analog circuit requirements.
• Ensures signal integrity through exceptionally low low-frequency noise performance.

Voltage Reference Applications

• High-resolution data acquisition systems requiring stable reference voltages
• Precision instrumentation circuits demanding low drift characteristics
• Calibration equipment utilizing accurate voltage standards

Voltage Reference Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm the E grade designation aligns with required accuracy specifications. Ensure the SOIC-8 footprint matches the target PCB layout constraints. Validate RoHS compliance status against current regulatory requirements before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when superior long-term stability and low noise are critical compared to standard LDO regulators. The fixed 5V output simplifies design by eliminating external resistor networks. Consider the 3.5mA quiescent current for power budget calculations. The wide input voltage range allows flexibility in supply rail selection without compromising regulation performance.

Voltage Reference Part Context

This part belongs to the LT1027 family of precision voltage references known for hermetic-grade stability in plastic packages. It serves as a direct replacement for older ceramic hermetic versions in modern surface-mount designs. The ECS8-5 variant specifically denotes the 5V output version in the 8-pin SOIC form factor, maintaining the legacy performance metrics of the original LT1027 series.

Voltage Reference Replacement Considerations

LT1027ECS8-5#PBF offers identical electrical specifications but utilizes tube packaging instead of tape-and-reel. Designers requiring reel packaging for automated assembly should strictly select the TRPBF suffix. Verify that pinout compatibility remains consistent across packaging variations to prevent board redesign efforts during substitution.
