LD39130S
Description
The
LD39130S
is a high accuracy voltage regulator that provides 300 mA maximum
current from an input voltage ranging from 1.4 V to 5.5 V, with a typical dropout
voltage of 300 mV.
It is available in DFN6 1.2 x 1.3 mm package and in ultra-small CSP 4 bumps
package, allowing the maximum space saving.
The device is stabilized with a ceramic capacitor on the output. The ultra-low drop
voltage, low quiescent current and low noise features make it suitable for low power
battery-operated applications. It integrates an internal logic circuitry, which allows the
regulator to be in ultra-low consumption mode (green mode), when the output current
required is very low. The normal working mode, with fast transient response, is
restored when the load current increases.
The enable logic control function puts the
LD39130S
in shutdown mode allowing a
total current consumption lower than 0.1 µA. The current foldback and thermal
protection are provided.
