Frequently Asked Questions
What is the maximum temperature coefficient drift of the LT1236?
The output voltage temperature coefficients vary by model, ranging from 2 ppm/°C for the A-series to 15 ppm/°C for the C-series.
Does it support both Series and Shunt operating modes?
Yes, the device is almost totally immune to input voltage variations and can function in either Series Mode (two-terminal zener) or Shunt Mode.
What are the maximum input/output voltage differential limits?
The LT1236 supports a high Input/Output Voltage Differential of 35V, with an output short-circuit duration up to 10 seconds.
What is the minimum detectable noise level for the output?
For frequencies between 0.1Hz and 10Hz, the output voltage noise is specified as low as 3.0 microvolt P-P.
