ZTR250 - Zetex Semiconductors

ZTR250 (ZTR250 / ZTR500) FIXED 2.5 AND 5 VOLT 3-TERMINAL VOLTAGE REFERENCES

The ZTR250 and ZTR500 are precision three terminal references. These devices are ideal for battery powered applications where power saving is important. They offer low power alternatives to other two terminal shunt references. The ZTR devices do not require an external resistor and, in contrast to two terminal references, waste none of the battery power as l.
