LD56100

Description

The LD56100 high accuracy voltage regulator provides 1 A of current from an input

voltage ranging from 1.8 V to 5.5 V, with a typical dropout voltage of 120 mV.

It is available in DFN8 (1.2 x 1.6 mm) 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 fast transient response, together with the internal

soft-start circuit, make the LD56100 suitable for low power battery-operated

applications.

An enable logic control function puts the LD56100 in shutdown mode allowing a total

current consumption lower than 0.1 µA. Short-circuit protection with current limit

foldback and thermal protection are also included.
