L7852CV datasheet by STMicroelectronics

L7852CV Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the L7852CV can handle?
  The L7852CV can handle a maximum input voltage of 35V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the L7852CV is stable and doesn't oscillate?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a minimum ESR (Equivalent Series Resistance) of 0.5 ohms. Also, keep the input and output capacitors close to the IC and use short leads.
• What is the maximum output current that the L7852CV can provide?
  The L7852CV can provide a maximum output current of 1.5A, but it's recommended to keep it below 1.2A for reliable operation and to prevent overheating.
• How do I calculate the output voltage of the L7852CV?
  The output voltage of the L7852CV can be calculated using the formula: Vout = Vref x (1 + R2/R1), where Vref is the internal reference voltage (2.5V), R1 and R2 are the resistors in the voltage divider network.
• What is the purpose of the 'EN' pin on the L7852CV?
  The 'EN' (Enable) pin is used to enable or disable the regulator. When the 'EN' pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
