Questions answered in these manuals
What protection features are built into the LM2931 series?
The LM2931 series includes internal current limiting, thermal shutdown, over‑voltage, reverse‑polarity input protection, and temporary mirror‑image protection.
What is the recommended output capacitor condition for stability?
The output capacitor impedance |Z₀| must not exceed 0.4 Ω over the full operating temperature range.
What is the maximum single‑supply voltage for the LM393 series?
The LM393 series can operate from 2 V up to 36 V on a single supply.
What is the typical supply current of the LM393 comparator?
Typical supply current is about 0.4 mA, independent of the supply voltage.
