General part information

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.
