1 / 6 page ![]() FIXED 2.5 AND 5 VOLT 3-TERMINAL VOLTAGE REFERENCES ISSUE 4 - MARCH 1998 DEVICE DESCRIPTION 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 load current varies. The ZTR only consumes 30 µA supply current. The two devices require as low as 1.4 volts between input and output for regulation. Output voltage tolerance is ± 2.5%, with a voltage variation of 0.275mV/°C over the -55°C to 125°C operating range. FEATURES • Small outline SOT23 and SOT89 packages • TO92 package • 2.5V and 5V output • 2.5% tolerance • Supply current independent of input voltage over temperature • Output current up to 50mA • Very low supply current (30µA) • Unconditionally stable • Internal short circuit current limit APPLICATIONS • Battery Powered Systems • Portable and Hand Held Equipment • Instrumentation • Metering ZTR250 ZTR500 Vin Vout Gnd SCHEMATIC DIAGRAM 4-388 Not Recommended for New Design Please Use ZMR Series |
