Instructions for Using TDE1767

1. Input Voltage (V_IN):

   • Ensure the input voltage is within the specified range of 2.7V to 5.5V.

2. Output Voltage (V_OUT):

   • The device provides a fixed output voltage of 3.3V. No external components are required for setting this voltage.

3. Output Current (I_OUT):

   • The device can supply up to 200mA continuously, with typical performance at 150mA.

4. Quiescent Current (I_Q):

   • The quiescent current is very low, typically around 2渭A, which makes it suitable for battery-operated applications.

5. Dropout Voltage (V_DROPOUT):

   • The dropout voltage is approximately 200mV at full load conditions, ensuring efficient operation even at low input voltages.

6. Power Supply Rejection Ratio (PSRR):

   • The device has a high PSRR of 60dB at 1kHz, effectively rejecting noise from the power supply.

7. Load and Line Regulation:

   • Both load and line regulation are excellent, with load regulation of 0.2% and line regulation of 0.05%/V, ensuring stable output voltage under varying conditions.

8. Operating Temperature (T_OP):

   • The device operates reliably over a wide temperature range from -40掳C to +85掳C.

9. Installation and Layout:

   • Place the device close to the load to minimize trace inductance and improve stability.
   • Use adequate bypass capacitors on both input and output to ensure stability and reduce noise.

10. Safety Considerations:

    • Ensure proper heat dissipation if operating near the maximum output current.
    • Avoid exceeding the maximum input voltage to prevent damage to the device.
