Overview
The LM336Z-5.0/NOPB is a precision 5.0V shunt regulator diode produced by Texas Instruments (formerly National Semiconductor). This monolithic IC voltage reference operates as a low temperature coefficient 5.0V zener diode with a dynamic impedance of 0.6Ω. It is designed to provide a stable voltage reference in various electronic circuits, including digital voltmeters, power supplies, and op-amp circuitry. The device is available in a three-lead transistor package, such as the TO-92 package, and can be used as either a positive or negative voltage reference due to its shunt regulator operation.
