Input Voltage: Ensure the input voltage is within the operating range of 2.7V to 5.5V. Exceeding this range can damage the device.
Output Voltage: The EL5170ISZ provides a fixed output voltage of 3.3V. This is suitable for powering low-power circuits and microcontrollers requiring this voltage level.
Output Current: The maximum continuous output current is 150mA. Avoid drawing more current to prevent overheating or damage.
Quiescent Current: The quiescent current is very low at 1.0μA under no load conditions, making it efficient for battery-operated devices.
Dropout Voltage: With a dropout voltage of 0.4V at full load, this regulator can operate efficiently even when the input voltage is close to the output voltage.
PSRR (Power Supply Rejection Ratio): The device offers good power supply rejection ratio of 70dB at 1kHz, reducing noise from the input power supply.
Line Regulation: Line regulation is excellent at 0.01%/V, ensuring stable output voltage over a wide range of input voltages.
Load Regulation: Load regulation is 0.05%/mA, providing stable output voltage even with varying load currents.
Capacitors: For optimal performance, place a 1μF ceramic capacitor between the input pin and ground, and another 1μF ceramic capacitor between the output pin and ground as close as possible to the device.
Thermal Considerations: Ensure adequate heat dissipation if operating near the maximum output current to avoid overheating.
