TL712CD datasheet by Texas Instruments

TL712CD Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the TL712CD?
  The TL712CD can operate from -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C.
• How do I ensure stability when using the TL712CD as a voltage regulator?
  To ensure stability, use a minimum output capacitance of 10uF, and ensure that the output capacitor has an ESR (Equivalent Series Resistance) of less than 5 ohms. Additionally, use a minimum input capacitance of 1uF.
• What is the maximum input voltage that the TL712CD can handle?
  The TL712CD can handle a maximum input voltage of 35V, but it's recommended to keep the input voltage below 30V for reliable operation.
• Can I use the TL712CD as a current regulator?
  Yes, the TL712CD can be used as a current regulator by connecting a resistor (RSENSE) between the output and the sense pin. The current limit is determined by the value of RSENSE and the internal reference voltage.
• How do I calculate the output voltage of the TL712CD?
  The output voltage of the TL712CD is determined by the resistive divider network connected to the adjust pin. The output voltage can be calculated using the formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (2.5V) and R1 and R2 are the resistors in the divider network.
