Instructions for LM202H

1. Power Supply Connection:

   • Connect the input voltage (V_IN) between 2.7V and 5.5V to the input pin.
   • Ensure a proper bypass capacitor (typically 0.1μF) is placed close to the input pin to minimize noise.

2. Output Configuration:

   • The output voltage (V_OUT) is fixed at 3.3V. No external resistors are required for voltage setting.
   • Place an output capacitor (recommended 1μF) close to the output pin to stabilize the output voltage.

3. Ground Connection:

   • Ensure a solid ground connection to maintain stability and performance.

4. Load Requirements:

   • The device can supply up to 150mA of load current. Ensure that the load does not exceed this limit to avoid overheating or damage.

5. Thermal Considerations:

   • For applications where the regulator might dissipate significant power, ensure adequate heat sinking or consider the thermal resistance of the package.

6. Transient Response:

   • The regulator has good transient response characteristics, but for rapid load changes, additional capacitance may be beneficial.

7. PCB Layout:

   • Keep traces short and wide to reduce inductance and resistance, especially for the input and ground connections.
