Instructions for Using TL7757CLP

  1. Power Supply Connection:

    • Connect the input voltage (VIN) to the input pin.
    • Ensure the input voltage is within the operating range (2.0 V to 6.0 V).
  2. Output Configuration:

    • The output voltage (VOUT) can be adjusted using external resistors.
    • Use the formula: VOUT = 1.24 * (1 + R2/R1) where R1 and R2 are the feedback resistors.
  3. Quiescent Current:

    • The quiescent current (IQ) is typically 60 μA and can go up to 100 μA under no load conditions.
  4. Dropout Voltage:

    • The dropout voltage (VDROP) is typically 0.5 V and can reach up to 1.0 V at an output current of 100 mA.
  5. Load and Line Regulation:

    • The load regulation is typically 0.1% and can go up to 0.5% over the load range from 0 mA to 100 mA.
    • The line regulation is typically 0.1% and can go up to 0.5% over the input voltage range from 2.0 V to 6.0 V.
  6. Output Noise:

    • The output noise is typically 40 μVrms and can go up to 60 μVrms over the frequency range from 10 Hz to 100 kHz.
  7. Thermal Shutdown:

    • The device will shut down if the temperature exceeds 160°C to prevent damage.
  8. Short-Circuit Protection:

    • The device includes short-circuit protection to safeguard against excessive current draw.
  9. Capacitor Selection:

    • Use appropriate capacitors on the input and output to ensure stability and filter out noise. Typically, 1 μF ceramic capacitors are recommended.
  10. PCB Layout:

    • Place the input and output capacitors as close as possible to the respective pins to minimize inductance and improve performance.

By following these instructions, you can effectively use the TL7757CLP in your circuit design.
