Product overview
Description
The LD56050 is a high accuracy voltage regulator, which provides 0.5 A of current. It is equipped with an NMOS pass transistor, whose gate is biased by a dedicated pin, thus allowing an ultra low-drop performance even at very low input voltages.
It is available in DFN4 1.2 x 1.2 package, allowing the maximum space saving.
The device is stabilized with a small ceramic capacitor on the output. The ultra low-drop, low quiescent current and short circuit current foldback make the LD56050 suitable for low power battery-operated applications.
An enable logic control function puts the LD56050 in shutdown mode allowing a total current consumption lower than 0.1 µA. Thermal protection is also included.
