LM336Z25

LM336Z25 Programmable Shunt Regulator Features Description • • • • • The LM336Z25 integrated circuit is a precision 2.5 V shunt regulator. The monolithic IC voltage reference operates as a low temperature coefficient 2.5 V Zener with 0.2 Ω dynamic impedance. A third terminal on the LM336Z25 allows the reference voltage and temperature coefficient to be trimmed. LM336Z25 is useful as a precision 2.5 V low-voltage reference for digital voltmeters, power supplies, or OP-AMP circuitry. The 2.5 V makes it convenient to obtain a stable reference from low-voltage supplies. Further, since the LM336Z25 operates as a shunt regulator, it can be used as either a positive or negative voltage reference. Low-Temperature Coefficient Guaranteed Temperature Stability: 4 mV (Typical) 0.2 Ω Dynamic Impedance 1.0% Initial Tolerance Available Easily Trimmed for Minimum Temperature Drift TO-92 1 1.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.
