Description

The ST1L08 provides 0.8 A of maximum current

from an input voltage in the range from 1 V to

5.5 V, with a typical dropout voltage as low as

70 mV.

It is stabilized with a ceramic capacitor on the

output.

The very low drop voltage, low quiescent current

and high PSRR features make it suitable for low

power battery-powered applications.

Enable logic control function puts the ST1L08 in

shutdown mode, reducing the total current

consumption.

Power Good function and input voltage control

feature the ST1L08Sxx version.

The device is equipped with current limit and

thermal protection.
