SOT23 MICROPOWER 1.22V VOLTAGE REFERENCE
ZXRE125
DESCRIPTION
The ZXRE125 is a bandgap circuit designed to achieve
a precision micropower voltage reference of 1.22
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 available to 0.5% for precision
applications. Excellent performance is maintained
over the 30µA to 5mA operating current range with a
FEATURES
• High performance replacement for ZRA124 and
ZRA125 references
• Small outline SOT23
• SO8 and E-Line alternatives available
• 30µA knee current
• 20ppm/°C typical temperature coefficient
• Unconditionally stable
• 0.5%, 1%, 2% and 3% tolerance
• Contact Zetex marketing for availability of tighter
tolerance devices
typical temperature coefficient of only 20ppm/°C. The
device has been designed to be highly tolerant of
capacitive loads so maintaining excellent stability.
This device offers a SOT23 pin for pin compatible
replacement of the ZRA124 and ZRA125 series of
voltage references. SO8 and E-Line (TO92 style)
packages can also be made available.
