?2001 fairchild semiconductor corporation www.fairchildsemi.com rev. 1.0.0 features ? low temperature coefficient ? adjustable 4v to 6v ? wide operating range current of 400ma to 10ma ? 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 ka336-5.0/ka336b-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 0.6ohm dynamic impedance. a third terminal on the ka336-5.0/ka336b-5.0 allow the reference voltage and temperature coefficient to be trimmed easily. the ka336-5.0/ka336b-5.0 are useful as a precision 5.0v low voltage references it convenient in obtaining a stable reference from low voltage supplies. further, since the ka336-5.0/ka336b-5.0 operate as shunt regulators, they can be used as either a positive or negative voltage reference. to-92 1 . adj 2.+ 3. - 1 internal block diagram ka336-5.0/ka336b-5.0 programmable shunt regulator
