DIODES INC. ZRC250F01TA SOT-23 Precision 2.5V Voltage Reference
Precision 2.5V shunt voltage reference from DIODES INC. Low power, stable with no external capacitor. Ideal for portable & test equipment.
The DIODES INC. ZRC250F01TA is a precision, low-power shunt voltage reference delivering a stable 2.5V output. It employs a sophisticated bandgap circuit design to provide a highly accurate micropower reference voltage, making it an ideal choice for space-constrained and power-sensitive designs.
A key advantage is its exceptional stability without the need for an external capacitor, simplifying board layout and reducing component count. The device is stable with capacitive loads and achieves a stable operating condition in under 10 microseconds, offering superior switching capability for dynamic applications.
It is optimised for low-power operation, with a recommended current range of 20μA to 5mA and a typical minimum operating current of just 13µA, making it perfectly suited for battery-powered and portable equipment. Its rugged design can handle transient currents up to 200mA and an absolute maximum of 25mA, ensuring reliability in demanding environments.
