Instructions for Use:
Power Supply Connection:
- Connect the input pin to a power supply within the specified voltage range.
- Ensure that the power supply is stable and within the operating temperature range.
Output Configuration:
- Connect the output pin to the load requiring regulated voltage.
- For optimal performance, place a bypass capacitor close to the output pin.
Grounding:
- Ensure a solid ground connection to maintain stability and minimize noise.
Thermal Considerations:
- Both devices are designed to operate within a wide temperature range but ensure adequate heat dissipation if operating at high currents or in high ambient temperatures.
Capacitor Selection:
- Use ceramic capacitors with X7R or X5R characteristics for input and output filtering.
- Recommended values are typically 1 μF for both input and output capacitors.
PCB Layout:
- Keep traces short and wide to reduce parasitic inductance and resistance.
- Place components close to the IC to minimize noise pickup.
Handling Precautions:
- These devices are sensitive to electrostatic discharge (ESD); use proper ESD protection measures during handling and assembly.
For detailed specifications and additional information, refer to the official datasheets provided by the manufacturer.
