ZRB500 Precision 5V micropower voltage reference Description 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. The ZRB500 uses a bandgap circuit design to achieve a precision micropower voltage reference of 5.0 volts. The device is available in small outline surface mount packages, ideal for applications where space saving is important, as well as packages for through hole requirements. The ZRB500 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The ZRB500 is recommended for operation between 50A and 15mA and so is ideally suited to low power and battery powered applications. 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 and TO92 style packages • Precision power supplies Typical application circuit VR + Gnd Issue 5 - May 2006 © Zetex Semiconductors plc 2006 1 www.zetex.com ZRB500 Connection diagrams VR Rounded face Pin 1 floating or connected to pin 2 La st 1 Gnd VR Gnd VR E-Line, 3 pin package suffix - A N o fo t r r ec ne o w mm de e si nd gn e s d 3 Rounded face bu y Gnd ti m e 2 E-Line, 3 pin, rev package suffix - R N o fo t r r ec ne o w mm de e si nd gn e s d E-Line, 2 pin package suffix - Y SOT23 package suffix - F Rounded face VR Gnd Ordering information Order reference ZRB500A01 ZRB500A01STOA ZRB500A01STOB ZRB500A01STZ ZRB500A02 ZRB500A02STOA ZRB500A02STOB ZRB500A02STZ ZRB500A03 ZRB500A03STOA ZRB500A03STOB ZRB500A03STZ ZRB500F01TA ZRB500F01TC ZRB500F02TA ZRB500F02TC ZRB500F03TA ZRB500F03TC ZRB500R01 ZRB500R01STOA ZRB500R01STOB ZRB500R01STZ ZRB500R02 ZRB500R02STOA ZRB500R02STOB ZRB500R02STZ ZRB500R03 ZRB500R03STOA Tol.
