Frequently asked questions
What is the price of LM317LZ Adjustable Positive Voltage Regulator 100mA TO-92 in Egypt?
LM317LZ Adjustable Positive Voltage Regulator 100mA TO-92 currently costs 3.5 EGP in Egypt.
Where can I buy LM317LZ Adjustable Positive Voltage Regulator 100mA TO-92 in Egypt?
LM317LZ Adjustable Positive Voltage Regulator 100mA TO-92 is available from Makers Electronics. Compare the offers above to find the best price.
How do I set the output voltage?
Use two resistors: R1 between OUT and ADJ (commonly 240 ohms) and R2 from ADJ to ground. The output is approximately Vout = 1.25 V × (1 + R2/R1). Confirm the values in the datasheet.
How do I check heat dissipation?
Power dissipated is approximately (Vin - Vout) × Iout. For example, 12 V in and 5 V out at 100 mA gives about 0.7 W, which is high for a TO-92 package, so keep the voltage drop small at higher currents.
