Instructions for HR202L

1. Installation:

   • Ensure the input voltage (V_IN) is within the operating range of 2.7V to 5.5V.
   • Connect the input capacitor (C_IN) and output capacitor (C_OUT) close to the device for stability. Recommended values are 1μF for C_IN and 1μF for C_OUT.

2. Operation:

   • The HR202L provides a fixed output voltage of 3.3V.
   • Ensure the load current does not exceed 200mA to avoid overheating or damage.
   • The quiescent current is very low at 1μA, making it suitable for battery-operated devices.

3. Thermal Considerations:

   • If operating near the maximum output current, ensure adequate heat dissipation to prevent thermal shutdown.

4. Troubleshooting:

   • If the output voltage is not stable, check the input and output capacitors and their placements.
   • Verify that the input voltage is within the specified range and that there are no shorts in the circuit.
