Description

LDLN050

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.

On the adjustable version, the output voltage can be set to any desired value

between 1.25 V and 6 V. Fixed voltage versions, between 1.0 V and 4.3 V (with

0.1 V step) can be provided upon request.

On the fixed voltage versions only, an external capacitor can be connected to C_NR

pin to further reduce the noise on the regulated output voltage.

The LDLN050 is available in DFN8 (3 x 3 mm) package.
