SOT23 MICROPOWER 1.225V VOLTAGE REFERENCE
Description
The ZXRE4041 is a bandgap circuit designed to achieve a
precision micropower voltage reference of 1.225 volts. The
device is available in the small outline SOT23 surface
mount package which is ideal for applications where space
saving is important.
SOT23 tolerance is avai lable to 0.5% C grade for precision
applications. Excellent performance is maintained over the
30A to 12mA operating current range with a typical
temperature coefficient of only 20ppm/°C. The device has
been designed to be highl y tolerant of cap aci tive loads so
maintaining excellent stability.
This device offers a SOT23 pin for pin compatible
alternative to LM4041 voltage references.
Features
• High performance alternativ e to LM4041
• Small outline SOT23
• 30μA knee current
• 20ppm/°C typical temperature coefficient
• Unconditionally stable
• 0.5%, 1%, and 2% tolerance
• Green molding compound (No Br, Sb)
Applications
• Battery powered equipment
• Precision power supplies
• Portable instrumentation
• Portable communication devices
• Notebook and palm top comp uters
• Data acquisition systems
• A/D and D/A converters
• Test equipment
