Instructions for Use:
Power Supply Connection:
- Connect the VCC pin to the power supply within the specified operating voltage range.
- Ensure the GND pin is connected to the ground.
Output Configuration:
- For adjustable output voltage, use an external resistor divider network between VOUT and GND to set the desired output voltage.
- For fixed output voltage, refer to the datasheet for specific resistor values.
Enable Function:
- The enable function can be controlled by applying a voltage greater than VEN to the EN pin. A voltage below VEN will place the device in shutdown mode.
Thermal Management:
- Ensure adequate heat dissipation, especially when operating at high currents or in high-temperature environments, to prevent thermal shutdown.
Short-Circuit Protection:
- The device has built-in short-circuit protection, but it is recommended to limit the duration of short-circuits to avoid excessive heating.
Capacitor Selection:
- Use appropriate input and output capacitors to stabilize the power supply and reduce ripple. Refer to the datasheet for recommended capacitor types and values.
Layout Considerations:
- Keep the layout compact to minimize parasitic inductance and capacitance.
- Place bypass capacitors close to the VCC and GND pins for optimal performance.
Storage and Handling:
- Store the device in a dry environment within the specified storage temperature range.
- Handle with care to avoid damage to the leads and package.
