Application information

The ST1L05 is a low-dropout linear regulator. It provides up to 1.3 A with a low 300 mV

dropout. The input voltage range is from 3 V to 5.5 V. The device is available in fixed and

adjustable output versions.

The regulator is equipped with internal protection circuitry, such as short-circuit current

limiting and thermal protection.

The regulator is designed to be stable with ceramic capacitors on the input and the output.

The expected values of the input and output ceramic capacitors are from 1 µF to 22 µF with

output capacitor has also to be connected 1 cm far from output pin. There isn’t any upper

limit to the value of the input capacitor.

Figure 24, Figure 25, Figure 26 and Figure 27 illustrate the typical application schematics:
