Instructions for Using TPS79101DBVR
Input Voltage:
- Ensure the input voltage is within the range of 1.7 V to 5.5 V.
- Use appropriate decoupling capacitors (typically 1 μF ceramic) close to the input pin to filter out noise.
Output Voltage:
- The output voltage is fixed at 1.0 V. No external resistors are needed for setting the output voltage.
Output Current:
- The device can provide up to 200 mA of continuous current.
- For higher current applications, consider using a more powerful LDO or a switching regulator.
Quiescent Current:
- The quiescent current is very low at 1.3 μA, making this LDO suitable for battery-powered devices.
Dropout Voltage:
- The dropout voltage is typically 200 mV. Ensure the input voltage is at least 200 mV higher than the output voltage to maintain regulation.
Load Regulation:
- The load regulation is 0.2%, meaning the output voltage will change by only 0.2% over the full load range from 0 to 200 mA.
Line Regulation:
- The line regulation is also 0.2%, indicating that the output voltage will change by only 0.2% over the input voltage range from 1.7 V to 5.5 V.
Power Supply Rejection Ratio (PSRR):
- At 1 kHz, the PSRR is 60 dB, which means the LDO effectively reduces high-frequency noise on the input.
Operating Temperature:
- The operating temperature range is from -40°C to 85°C. Ensure the device operates within this range to avoid thermal stress.
Storage Temperature:
- The storage temperature range is from -65°C to 150°C. Store the device in a dry, cool place to prevent damage.
PCB Layout:
- Place the input and output capacitors as close as possible to the LDO to minimize parasitic inductance and improve stability.
- Use wide traces for power and ground connections to reduce resistance and inductance.
Thermal Considerations:
- The TPS79101DBVR is designed to operate efficiently, but ensure proper heat dissipation if used in high-power applications or in environments with limited airflow.
Capacitor Selection:
- Use X7R or C0G type ceramic capacitors for both input and output to ensure stable operation and minimal ESR.
By following these guidelines, you can ensure optimal performance and reliability of the TPS79101DBVR in your application.
