Instructions for Using GS7133SO-R
Input Voltage (VIN):
- Ensure the input voltage is within the range of 2.7 V to 5.5 V.
- Use appropriate input filtering capacitors to stabilize the input voltage.
Output Voltage (VOUT):
- The output voltage can be adjusted using external resistors R1 and R2.
- The formula to calculate the output voltage is: ( V_ = 1.23 left(1 + fracright) ).
Quiescent Current (IQ):
- The quiescent current is typically 1.0 μA when no load is connected.
- This low quiescent current makes the device suitable for battery-powered applications.
Output Current (IOUT):
- The maximum continuous output current is 300 mA.
- Ensure the load does not exceed this limit to avoid overheating or damage.
Dropout Voltage (VDROPOUT):
- The dropout voltage is typically 120 mV at a 300 mA load.
- This low dropout voltage allows the regulator to operate efficiently even when the input voltage is close to the output voltage.
Load Regulation:
- The load regulation is 0.5% from 10 mA to 300 mA.
- This indicates that the output voltage remains stable over a wide range of load currents.
Line Regulation:
- The line regulation is 0.1% per volt.
- This means the output voltage changes minimally with variations in the input voltage.
PSRR (Power Supply Rejection Ratio):
- The PSRR is 70 dB at 1 kHz.
- This high PSRR helps in rejecting noise from the input power supply.
Operating Temperature:
- The device can operate in temperatures ranging from -40°C to 125°C.
- Ensure the operating environment is within these limits to maintain reliable performance.
Storage Temperature:
- The storage temperature range is from -65°C to 150°C.
- Store the device in a dry and cool place to prevent damage.
Capacitor Selection:
- Use ceramic capacitors for both input and output to ensure stability and minimize ripple.
- Typical values are 1 μF for the input and 1 μF for the output.
PCB Layout:
- Place the input and output capacitors as close as possible to the regulator to reduce parasitic inductance.
- Use wide traces for power lines to minimize voltage drops and heating.
By following these guidelines, you can ensure optimal performance and reliability of the GS7133SO-R regulator in your application.
