| www.fairchildsemi.com LM336-5.0/LM336B-5.0 Programmable Shunt Regulator Features * * * * * * * * * Low Temperature Coefficient Adjustable 4V to 6V Wide Operating Range Current of 10mA to 400mA Three Lead Transistor Package (TO-92) 0.6 OHM Dynamic Impedance 1.0% Initial Tolerance Available Guaranteed Temperature Stability Easily Trimmed for Minimum Temperature Drift Fast Turn On Description The LM336-5.0 / LM336B-5.0 integrated circuits are precision 5.0V shunt regulators. The monolithic IC voltage reference operates as a low temperature coefficient 5.0V zener with 0.6 ohm dynamic impedance. A third terminal on the LM336-5.0/LM336B-5.0 allows the reference voltage and temperature coefficient to be trimmed easily. The LM336-5.0/LM336B-5.0 are useful as a precision 5.0V low voltage references which makes it convenient to obtain a stable reference from low voltage supplies. Further, since the LM336-5.0/LM336B-5.0 operate as shunt regulators, they can be used as either a positive or negative voltage reference. TO-92 1 1.
