A Product Line of Diodes Incorporated ZRB500 PRECISION 5V MICROPOWER VOLTAGE REFERENCE Description Pin Assignments The ZRB500 uses a bandgap circuit design to achieve a precision micropower voltage reference of 5.0 volts. The SOT23 Package Suffix F device is available in small outline surface mount packages, ideal for applications where space saving is important, as 2 GND well as packages for through hole requirements. 1 The ZRB500 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The V 3 R ZRB500 is recommended for operation between 50A and 15mA and so is ideally suited to low power and battery (Top View) powered applications. Pin 1 floating or connected to pin 2 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 Applications 3%, 2% and 1% tolerance Battery powered and portable equipment Operating current 50A to 15mA Metering and measurement systems Typical TC 15ppm/C Instrumentation Transient response, stable in less than 10s Test equipment Industrial temperature range Data acquisition systems Small outline SOT23 style package Precision power supplies Green molding compound (No Br, Sb) Typical Application Circuit V R - + GND 1 of 5 March 2012 ZRB500 Diodes Incorporated www.diodes.com Document number: DS32240 Rev. 6 - 2 A Product Line of Diodes Incorporated ZRB500 PRECISION 5V MICROPOWER VOLTAGE REFERENCE Absolute Maximum Ratings (Voltages to GND Unless Otherwise Stated) Parameter Rating Unit Reverse Current 25 mA Forward Current 25 mA Operating Temperature -40 to 85 C Storage Temperature -55 to 125 C Power Dissipation (T = 25C) AMB 330 mW SOT23 Electrical Characteristics (Test conditions: T = 25C, unless otherwise specified.)
