ST1L08

800 mA ultra low drop, high PSRR voltage regulator

Datasheet - production data

Applications



Consumer

Hard disk drives, SSD

Computer

Battery-powered systems

Low voltage point of load

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.

Features



Input voltage from 1 to 5.5 V

Ultra low-dropout voltage (90 mV max. @

800 mA load)

The very low drop voltage, low quiescent current

and high PSRR features make it suitable for low

power battery-powered applications.



Low ground current (35 μA typ. @ no load)

Output voltage tolerance: ± 2.0% @ 25 °C

High PSRR: 80 dB @ 100 Hz, 50 dB @

1 MHz

Enable logic control function puts the ST1L08 in

shutdown mode, reducing the total current

consumption.



800 mA guaranteed output current

Wide range of output voltages available on

request: from 0.5 V to 4 V and adjustable

Logic-controlled electronic shutdown

Internal current and thermal limit

Power Good function

Available in DFN8 2x3 mm package

Temperature range: -40 °C to 125 °C

Input voltage control for the ST1L08Sxx

Power Good function and input voltage control

feature the ST1L08Sxx version.



The device is equipped with current limit and

thermal protection.
