Description

General part information

LDLN050 Series

The LDLN050 is a 500 mA LDO regulator, designed to be used in several environments. The LDLN050 has a very low-resistance pass element (PMOS) that is even very fast during the turn-on.

Thanks to its low-noise design, the LDLN050 can be used to supply noise sensitive circuits such as sensors, MCUs and wireless ICs in industrial applications.

The LDO low current consumption (typically 48 µA) is also used on battery-supplied applications.
