4. Marking Information

️· First Voltage Digit: Represented by a symbol (likely a code)
️· First Decimal Place Voltage: Another symbol (A-M), corresponding to tenths place values (e.g., A=0.0, B=0.1,...M=0.9)
️· Polarity: Symbol "0" denotes a positive voltage.

Key Terminology Explained

️· Dropout Voltage: The difference between the input voltage and the output voltage at which the regulator is still functioning correctly. A lower dropout voltage is better.
️· Output Voltage Regulation: How much the output voltage changes under different conditions (load, temperature).
️· I/O Voltage Difference: Difference between input and output voltage.
️· Temperature Coefficient: How the output voltage changes with temperature.
️· Long-Term Stability: How much the output voltage changes over time under stress conditions.
