ZRA245
PRECISION 2.45 VOLT VOLTAGE REFERENCE
DEVICE DESCRIPTION
The ZRA245 uses a bandgap circuit design to achieve
a precision voltage reference of 2.45 volts. The
device is available in small outline surface mount
packages, ideal for applications where space saving
is important.
The ZRA245 design provides a stable voltage
without an external capacitor and is stable with
capacitive loads. The ZRA245 is recommended for
operation between 2mA and 120mA.
