LDLN050

DFN8 (3 x 3 mm) Maturity status link LDLN050 LDLN050 Datasheet 500 mA, high performance low dropout linear regulator Features Input voltage range: 2.7 V to 6.5 V Very low output voltage noise: 13 µVRMS/VOUT Low quiescent current: 48 µA typical 500 mA guaranteed output current Fast start-up time: 50 µs High PSRR: 65 dB at 100 Hz -40 °C to 125 °C ambient operative temperature range Very low dropout: 190 mV at max. IOUT Adjustable (from 1.25 V to 6 V) or fixed output voltage on request (from 1.0 V to 4.3 V) Stable with low ESR capacitor: min. 2 µF Current limit and thermal protections DFN8 (3 x 3 mm) standard for industrial Application Low noise POL Wireless communication Industrial applications Description 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 CNR pin to further reduce the noise on ...
