Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the operating range of 4.5V to 28V.

2. Output Voltage (VOUT):

   • The NJW1151M(TE1) provides a fixed output voltage of 3.3V.

3. Output Current (IOUT):

   • The device can supply up to 1.5A continuously. Avoid exceeding this limit to prevent damage.

4. Quiescent Current (IQ):

   • The quiescent current is typically 60μA at VIN = 12V and VOUT = 3.3V.

5. Dropout Voltage (VDROPOUT):

   • At an output current of 500mA, the dropout voltage is typically 500mV.

6. PSRR (Power Supply Rejection Ratio):

   • The PSRR at 1kHz is typically 70dB, indicating good noise rejection from the input supply.

7. Line Regulation:

   • Line regulation is typically 0.05% at an output current of 500mA, ensuring stable output despite changes in input voltage.

8. Load Regulation:

   • Load regulation is typically 0.1% at VIN = 12V, ensuring stable output despite changes in load current.

Additional Notes:

• Always ensure proper heat dissipation if operating near the maximum output current.
• Use appropriate capacitors on the input and output for stability and transient response.
• Refer to the datasheet for detailed application circuits and layout recommendations.
