ZR431LF01TA Integrated Circuits (ICs)

The ZR431LF01TA is a monolithic voltage reference that belongs to the PMIC - Voltage Reference category. It is designed to provide a stable and accurate input/output voltages. It offers excellent accuracy, temperature drift, and long-term stability at a low cost.

The ZR431LF01TA is a three-terminal voltage reference IC with an output voltage tolerance of +/- 0.10% and a thermal stability at rated temperature of +/- 0.02%/°C. It is available in an industry-standard SIP package.

The ZR431LF01TA is ideal for use in applications requiring low cost, stable, and accurate voltage references. Examples include music and audio systems, navigation systems, and communication systems. It can also be used in voltage test and measurement systems, such as digital multimeters, to provide a stable and accurate reference voltage.

The ZR431LF01TA operates on a battery voltage of 2.5V to 10V and offers a selectable output voltage range of 2.5V to 8.0V. It features a high-impedance current limiter with a maximum output current of 23mA. It has a temperature range of -40°C to +85°C and is specified for operation from 0°C to +70°C.

The ZR431LF01TA has two modes of operation: a low-impedance mode for a constant output current and a high-impedance mode for a constant output voltage. In the low-impedance mode, the reference voltage is set by the voltage drop across an internal resistor, and the output current is limited by external resistor to a maximum current of 23 mA. In the high-impedance mode, the voltage across the internal resistor is modulated to generate an output voltage.

The ZR431LF01TA is designed to provide a low cost, stable and accurate voltage reference for a wide range of applications. It offers excellent accuracy, temperature drift, and long-term stability. Its wide operating voltage range, and small form factor make it ideal for use in a variety of applications.
