Input Connection:
- Connect the input voltage (VIN) between the VIN pin and GND. Ensure the input voltage is within the specified range of 2.7V to 5.5V.
Output Configuration:
- The LD5760TGR provides a fixed output voltage of 3.3V. No external components are required for setting the output voltage.
Capacitor Requirements:
- Place a 1μF ceramic capacitor between the VOUT pin and GND as close as possible to the device for stability.
- A 1μF ceramic capacitor is also recommended between the VIN pin and GND to filter noise and transients.
Thermal Considerations:
- Ensure adequate heat dissipation, especially when operating near the maximum output current. The device can operate up to 85°C ambient temperature.
Quiescent Current:
- The quiescent current is very low (2.5μA), making it suitable for battery-operated devices where power consumption is critical.
Dropout Voltage:
- The typical dropout voltage is 180mV at full load, allowing the regulator to maintain regulation even when the input voltage is close to the output voltage.
Application Notes:
- For best performance, follow PCB layout guidelines closely, ensuring short leads and proper grounding practices.
- Test the circuit under all expected operating conditions to ensure stable and reliable operation.
