| 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. FEATURES APPLICATIONS * Small outline SOT23, SO8 and TO92 style package * Battery powered and portable equipment. * Metering and measurement systems. * Instrumentation. * Test equipment. * Data acquisition systems. * Precision power supplies. * No stabilising capacitor required * Typical TC 15ppm/C * Typical slope resistance 0.26 * 3% , 2% and 1% tolerance * Industrial temperature range * Operating current 2mA to 120mA SCHEMATIC DIAGRAM VR 1.25VREF GND ISSUE 4 -- JANUARY 2006 1 SEMICONDUCTORS ZRA245 ABSOLUTE MAXIMUM RATING Reverse Current Forward Current Operating Temperature Storage Temperature 200mA 25mA -40 to 85C -55 to 125C Power Dissipation (Tamb=25C) SOT23 E-Line, 3 pin (TO92) E-Line, 2 pin (TO92) SO8 330mW 500mW 500mW 625mW ELECTRICAL CHARACTERISTICS TEST CONDITIONS (Unless otherwise stated) Tamb=25C SYMBOL PARAMETER CONDITIONS LIMITS MIN.
