LD57100J330R

LD57100J330R is a 1A ultra low-dropout LDO with bias. It is a high-accuracy voltage regulator, which provides 1A of current. It is equipped with an NMOS pass transistor, whose gate is biased by a dedicated pin, thus allowing ultra-low drop performance even at very low input voltages. This device is stabilized with a small ceramic capacitor on the output. The ultra-low drop, low quiescent current and short-circuit protection make the LD57100 suitable for low-power battery-operated applications. An enable logic control function puts the LD57100 in shutdown mode allowing a total current consumption lower than 0.1µA. Thermal protection is also included. The application includes smartphones, cameras, low voltage, and low noise post-regulation.
