LM136-2.5-N

LM136-2.5-N www.ti.com SNVS749F – MAY 1998 – REVISED APRIL 2013 LM136-2.5-N, LM236-2.5-N, LM336-2.5-NV Reference Diode Check for Samples: LM136-2.5-N FEATURES 1 2 Low Temperature Coefficient Wide Operating Current of 400 μA to 10 mA 0.2Ω Dynamic Impedance ±1% Initial Tolerance Available Specified Temperature Stability Easily Trimmed for Minimum Temperature Drift Fast Turn-On DESCRIPTION The LM136-2.5-N/LM236-2.5-N and LM336-2.5-N integrated circuits are precision 2.5V shunt regulator diodes. These monolithic IC voltage references operate as a low-temperature-coefficient 2.5V zener with 0.2Ω dynamic impedance. A third terminal on the LM136-2.5-N allows the reference voltage and temperature coefficient to be trimmed easily. The LM136-2.5-N series is useful as a precision 2.5V low voltage reference for digital voltmeters, power supplies or op amp circuitry. The 2.5V make it convenient to obtain a stable reference from 5V logic supplies. Further, since the LM136-2.5-N operates as a shunt regulator, it can be used as either a positive or negative voltage reference. The LM136-2.5-N is rated for operation over −55°C to +125°C while the LM236-2.5-N is rated over a −25°C to +85°C temperature range. The LM336-2.5-N is rated for operation over a 0°C to +70°C temperature range. See the connection diagrams for available packages.
