AS1364

Datasheet AS1364 1 A , L o w - D r o p o u t L i n e a r Vo l ta g e R e g u l a t o r www.DataSheet4U.com 1 General Description The AS1364 is a low-dropout linear regulator (LDO) designed to operate from 2V to 5.5V input, that delivers a wide range of highly accurate (±0.75%) factorytrimmed output voltages as well as adjustable output voltages (using an external resistor-divider network). The ultra-low dropout device requires only 140mV dropout voltage while delivering a guaranteed 1A load current and is therefore perfectly suited for battery-operated portable applications. Additionally the AS1364 offers extremly low 10µVRMS (100Hz to 100kHz) or 45µVRMS (10Hz to 1MHz) output voltage noise. Table 1.
