Description

The ZRB500 uses a bandgap circuit design to achieve a

precision micropower voltage reference of 5.0 volts. The

device is available in small outline surface mount packages,

ideal for applications where space saving is important, as

well as packages for through hole requirements.

The ZRB500 design provides a stable voltage without an

external capacitor and is stable with capacitive loads. The

ZRB500 is recommended for operation between 50µA and

15mA 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.

Features

• ± 3%, ± 2% and 1% tolerance

• Operating current 50µA to 15mA

• Typical TC 15ppm/°C

• Transient response, stable in less than 10µs

• Industrial temperature range

• Small outline SOT23 style package

• Green molding compound (No Br, Sb)
