LM336Z5 Programmable Shunt Regulator Features Description • • • • • • • • • The LM336Z5 integrated circuit is precision 5.0 V shunt regulator. The monolithic IC voltage reference operates as a low temperature coefficient 5.0 V Zener with 0.6 Ω dynamic impedance. A third terminal on the LM336Z5 allows the reference voltage and temperature coefficient to be trimmed. The LM336Z5 is useful as a precision 5.0 V low-voltage reference, which makes it convenient to obtain a stable reference from low-voltage supplies. Further, since the LM336Z5 operates as shunt regulator, it can be used as either a positive or negative voltage reference. Low Temperature Coefficient Adjustable 4 V to 6 V Wide Operating Range Current: 10 mA to 400 mA Three Lead Transistor Package (TO-92) 0.6 Ω Dynamic Impedance ±1.0% Initial Tolerance Available Guaranteed Temperature Stability Easily Trimmed for Minimum Temperature Drift Fast Turn On TO-92 1 1.

Schematic Diagram Absolute Maximum Ratings(1) Stresses exceeding the absolute maximum ratings may damage the device. 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. Symbol Value Unit IR Reverse Current Parameter 15 mA IF Forward current 10 mA 0 ~ +70 °C -60 ~ +150 °C TOPR Operating Temperature Range TSTG Storage Temperature Range Note: 1. The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. © 2002 Fairchild Semiconductor Corporation Programmable Shunt Regulator Rev. 1.1.0 www.fairchildsemi.com 2 0°C ≤ TA ≤ +70°C unless otherwise specified.

ANTI-COUNTERFEITING POLICY Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com, under Sales Support. Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
