LM317 vs REG 101
LM317 and REG101 are both voltage regulators, but they have some differences in terms of their features and applications.
The LM317 is a popular linear voltage regulator that provides a regulated output voltage with adjustable values. It has a wide input voltage range and can handle higher currents. The output voltage can be adjusted using two external resistors, making it versatile for various applications. However, the LM317 has a relatively higher dropout voltage, which means the input voltage should be higher than the desired output voltage by a certain amount for proper regulation.
On the other hand, the REG101 is a low-dropout (LDO) voltage regulator specifically designed for low-power applications. It offers a fixed output voltage without the need for external resistors. The REG101 has a lower dropout voltage compared to the LM317, making it suitable for applications where the input voltage is close to the desired output voltage. It also provides better line and load regulation, ensuring a stable output voltage even with varying input conditions.
How to use REG 101?
Using the REG101 voltage regulator is quite straightforward. Here are the basic steps:
Step 1:
Determine the required output voltage for your application. The REG101 comes in different fixed output voltage options, so choose the one that matches your requirements.
Step 2:
Connect the input pin (VIN) of the REG101 to the power source or input voltage. Make sure the input voltage does not exceed the maximum specified limit mentioned in the datasheet.
Step 3:
Connect the output pin (VOUT) of the REG101 to your load or the circuit that requires the regulated voltage.
Step 4:
Connect the ground pin (GND) of the REG101 to the common ground of your circuit.
Step 5:
Add necessary input and output capacitors as recommended in the datasheet to improve stability and reduce noise.
Step 6:
Apply power to the input pin and check the output voltage using a multimeter. Ensure that the measured output voltage matches the desired output voltage.
