Features and benefits

* Input voltage from 2.5 V to 6 V
* Stable with low ESR ceramic capacitors
* Ultra low-dropout voltage (60 mV typ. at 150 mA load, 0.4 mV typ. at 1 mA load) <.

Application

and in battery-powered systems. Regulator ground current increases slightly in dropout only, prolonging the battery life.

Description

The LD3985 provides up to 150 mA, from 2.5 V to 6 V input voltage. The ultra low drop voltage, low quiescent current and low noise make it suitable for low power applications and in battery-powered systems. Regulator ground current increases slightly.
