Overview
The TS4041EIZ-1.2 is a micropower shunt voltage reference manufactured by STMicroelectronics, providing a stable 1.225V output voltage with ±2% precision at 25°C. It operates within an industrial temperature range of -40°C to +85°C and features a maximum temperature coefficient of 150ppm/°C. The device requires a minimum operating current of 65µA at 25°C and supports up to 12mA. It is housed in a TO92 plastic package.
Feature Summary
- Ultra-low operating current suitable for power-restricted designs
- High stability when used with capacitive loads
- Compact surface mount or through-hole packaging options
Applications
- Computers
- Instrumentation
- Battery chargers
- Switch Mode Power Supply
- Battery operated equipments
Procurement Notes
Verify the specific ordering suffix 'Z' corresponds to the TO92 plastic package configuration as documented in the official datasheet. Confirm that the 'E' designation aligns with the required ±2% precision tolerance level for your design specifications. Ensure compatibility with the specified industrial temperature range limits during component sourcing.
Selection Notes
Select this component for applications requiring a precise 1.225V reference with low quiescent current consumption. The TO92 package is suitable for designs where space constraints are less critical than through-hole mounting preferences. Consider the ±2% initial accuracy and 150ppm/°C temperature coefficient against system requirements for voltage stability across the operating temperature range.
Part Context
This part belongs to the TS4041 family of micropower shunt voltage references from STMicroelectronics. The series includes variants with different precision levels (±0.5%, ±1%, ±2%) and package types, including SOT23-3L and TO92. The TS4041EIZ-1.2 specifically denotes the 2% precision version in the TO92 package.
Replacement Considerations
Compatible substitutes include TS4041DIZ-1.2 for 1% precision and TS4041CIZ-1.2 for 0.5% precision within the same TO92 package. Surface-mount equivalents such as TS4041EILT-1.2 offer identical electrical characteristics in a SOT23-3L package.
