  • 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 automotive and 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 CNR pin to further reduce the noise on the regulated output voltage.
    The LDLN050 is available in DFN8 (3 x 3 mm) standard and wettable flank package and it is automotive grade qualified according to AEC-Q100 level 1.
