Description
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 50A 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⍀ Ϯ 1% tolerance Industrial temperature range Operating current 50A to 5mA No stabilising capacitor required Transient response, stable in less than 10s Small SOT23 package
