Texas Instruments LM336Z-2.5 Voltage Reference Diode, 2.49V, TO-226AA
Precision 2.49V shunt voltage reference diode from Texas Instruments. Low TC, 0.2Ω impedance, ideal for power supplies.
The Texas Instruments LM336Z-2.5 is a precision voltage reference diode integrated circuit, designed to provide a stable 2.5V shunt reference with excellent temperature stability and low dynamic impedance. This monolithic IC operates with a wide current range of 400µA to 10mA, making it highly versatile for various power management and analogue circuitry applications.
Featuring a third terminal for easy trimming, the reference voltage and temperature coefficient can be adjusted to minimise temperature drift, ensuring accurate performance across varied operating conditions. With an initial tolerance of ±1% and a temperature coefficient of 34ppm/°C, this device guarantees reliable and consistent output over a temperature range of 0°C to 70°C.
The LM336Z-2.5 is particularly useful for deriving a stable reference from 5V logic supplies and can be configured as either a positive or negative voltage reference due to its shunt regulator topology. Its 0.2Ω dynamic impedance and fast turn-on response further enhance its suitability for precision applications.
This product is green and free from antimony and bromine, aligning with modern environmental standards. Housed in a compact TO-226AA package with 3 pins, it is designed for easy integration into a wide range of electronic circuits.
