ZXRE4041
SOT23 MICROPOWER 1.225V VOLTAGE REFERENCE
DESCRIPTION
range with a typical tem perature coefficient of only
20ppm /°C. The device has been designed to be highly
tolerant of capacitive loads so maintaining excellent
stability.
The ZXRE4041 is a bandgap circuit designed to
achieve a precision m icropower voltage reference of
1.225 volts. The device is available in the small outline
SOT23 surface m ount package which is ideal for
applications where space saving is important.
This device offers a SOT23 pin for pin compatible
alternative to LM4041 voltage references. SO8 and
E-Line (TO92 style) packages can also be m ade
available.
SOT23 tolerance is available to 0.5% C grade for
pre cision applications. Excellent perform ance is
m aintained over the 30 A to 12mA operating current
