Typical Applications
High Stability 1 Amp Regulator
776706
Lead and line regulation — 0.01% temperature stability — 0.2%
†Determines Zener current.
††Solid tantalum.
An LM120-12 or LM120-15 may be used to permit higher input voltages, but the regulated output voltage must be at least −15V when using the LM120-12 and
−18V for the LM120-15.
**Select resistors to set output voltage. 2 ppm/°C tracking suggested.
Wide Range Tracking Regulator
776707
*Resistor tolerance of R1 and R2 determine matching of (+) and (−) inputs.
**Necessary only if raw supply capacitors are more than 3 from regulators
An LM3086N array may substitute for Q1, D1 and D2 for better stability and tracking. In the array diode transistors Q5 and Q4 (in parallel) make up D2; similarly,
Q1 and Q2 become D1 and Q3 replaces the 2N2222.
