LM78L 05 ACZ

Crambone:
Guys how can I test this correctly? I put in a cheap Chinese transistor tester and it shows the following as seen in picture.

Kim Christensen:
Those testers can't check a LM78L05... Because it's not a transistor, FET, diode, capacitor, resistor, etc.
They don't check IC voltage regulators, which is what a LM78L05 is.

Crambone:
OK thanks I figured it wasn’t testing it correctly. I tested voltages in circuit and it’s working properly after I found a 100uf cap that tested 17uf.

barshatriplee:
The easiest way to check these voltage regulator ICs is to use a multimeter and a DC power supply. Give the appropriate input voltage according to the datasheet. And see if you are getting the desired output voltage in the output pin.

What made you think the tester wasn't working? It's a transistor tester, yet the L78L05 is a voltage regulator, an integrated circuit, not a transistor. The only way to test it is to build a circuit with it.
