PRECISION 2.5 VOLT MICROPOWER VOLTAGE REFERENCE
ISSUE 2 - FEBRUARY 1998
ZR25D
DEVICE DESCRIPTION
The ZR25D uses a bandgap circuit design to achieve a precision micropower voltage reference of 2.5 volts. The device is available in a small outline SOT23 surface mount package, ideal for applications where space saving is important. The ZR25D design provides a stable voltage without an external capacitor and is stable with capacitive loads. The ZR25D is recommended for operation between 50µA 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.
