DEVICE DESCRIPTION

The ZRA124 uses a bandgap circuit design to achieve a

precision micropower voltage reference of 1.24 volts.

The device is available in a small outline surface mount

packages, ideal for applications where space saving is

important.

The ZRA124 design provides a stable voltage without

an external capacitor and is stable with capacitive

loads. The ZRA124 is recommended for operation

between 50 A and 5mA and so is ideally suited to low

power and battery powered applications.

Excellent performance is maintained to an absolute

maximum of 25mA, however the rugged design and 20

volt processing allows the reference to withstand

transient effects and currents up to 200mA. Superior

switching capability allows the device to reach stable

operating conditions in only a few microseconds.
