描述 Description

The LD56020 is a high accuracy voltage regulator which provides 0.2 A of current.

It is available in CSP 0.65 x 0.65 mm2 package, SOT23-5L, allowing the maximum

space saving.

The device is stabilized with a small ceramic capacitor on input and output. The

ultra-low drop, low quiescent current and short-circuit current foldback make the

LD56020 suitable for low power battery-operated applications.

An enable logic control function puts the LD56020 in shutdown mode allowing a total

current consumption lower than 0.1 μA. Thermal protection is also included.
