| ZRA124 PRECISION 1.24 VOLT MICROPOWER VOLTAGE REFERENCE 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. FEATURES * Typical TC 30ppm/C * Typical slope resistance 0.65 * 1% tolerance * Industrial temperature range * Operating current 50 A to 5mA * No stabilising capacitor required * Transient response, stable in less than 10 s * Small SOT23 package SCHEMATIC DIAGRAM APPLICATIONS * Battery powered and portable equipment * Metering and measurement systems * Instrumentation * Precision power supplies * Test equipment * Data acquisition systems TOP VIEW Pin 1 floating or connected to pin 2 ORDERING INFORMATION DEVICE ZRA124F01TA TOL % 1 REEL SIZE 7" TAPE WIDTH 8mm REEL QUANTITY 3,000 PART MARK 12C ISSUE 3 - JUNE 2004 1 SEMICONDUCTORS ZRA124 ABSOLUTE MAXIMUM RATING Reverse current Forward current Operating temperature Storage temperature 25mA SOT23 25mA -40 to 85C -55 to 125C 330mW Power dissipation (Tamb = 25C) ELECTRICAL CHARACTERISTICS TEST CONDITIONS (Unless otherwise stated) Tamb=25C SYMBOL PARAMETER CONDITIONS LIMITS MIN.
