Code: UJ57M

Product details

L78S15CV 2A 15V Positive Fixed Voltage Regulator

This positive 15V fixed voltage regulator has a quiescent current of 8mA, a short circuit current of 500 mA, a ripple rej. of between 46 and 54dB and is housed in a TO220 style case. The output voltage has a tolerance of ±4%. The input voltage range has an upper limit of +35V.

Am I correct in saying this regulator only needs a 0.33uf capacitor at the input & 0.1uf capacitor at the output or will it require something like a 470uf capacitor at the input for reasonable smoothing. Thank you.

This would entirely depend what you are using the item for, unfortunately we do not have enough information here to answer this fully.

Yes you can put them in parallel to double the current rating.

Can I put two or more of these regulators (of the same voltage) in parallel with a common heatsink to increase the load current? eg two 9V 2A regulators in parallel to increase current output to 4A).
