LM113

LM113, LM313 www.ti.com SNVS747 – SEPTEMBER 2011 LM113/LM313 Reference Diode Check for Samples: LM113, LM313 FEATURES 1 2 Low Breakdown Voltage: 1.220V Dynamic Impedance of 0.3Ω From 500 μA to 20 mA Temperature Stability Typically 1% Over −55°C to 125°C Range (LM113), 0°C to 70°C (LM313) Tight Tolerance: ±5%, ±2% or ±1% The characteristics of this reference recommend it for use in bias-regulation circuitry, in low-voltage power supplies or in battery powered equipment. The fact that the breakdown voltage is equal to a physical property of silicon—the energy-band gap voltage—makes it useful for many temperature-compensation and temperaturemeasurement functions. DESCRIPTION The LM113/LM313 are temperature compensated, low voltage reference diodes. They feature extremelytight regulation over a wide range of operating currents in addition to an unusually-low breakdown voltage and good temperature stability. The diodes are synthesized using transistors and resistors in a monolithic integrated circuit. As such, they have the same low noise and long term stability as modern IC op amps. Further, output voltage of the reference depends only on highly-predictable properties of components in the IC; so they can be manufactured and supplied to tight tolerances.
