LT3015EDD#PBF

LT®3015 series is low noise low dropout negative linear regulator with fast transient response. Quiescent current is also well controlled in dropout. In addition to fast transient response, the LT3015 series exhibit very low output noise, making them ideal for noise sensitive applications. The LT3015 regulators are stable with a minimum 10µF output capacitor. Moreover, the regulator can use small ceramic capacitors without the necessary addition of ESR as is common with other regulators. Internal protection circuitry includes reverse output protection, precision current limit with foldback and thermal limit with hysteresis. Applications are post-regulator for switching supplies, negative logic supplies, low noise instrumentation, industrial supplies.
