LT3015 - 1.5A, Low Noise, Negative Linear Regulator with ...

1 LT3015 Series13015fbThe LT 3015 series are low noise, low dropout, Negative Linear regulators with fast transient response. The devices supply up to of output current at a typical dropout voltage of 310mV. Operating quiescent current is typically and drops to < 1 A in shutdown. Quiescent current is also well controlled in dropout. In addition to fast tran-sient response, the LT3015 series exhibit very low output noise, making them ideal for noise sensitive LT3015 regulators are stable with a minimum 10 F 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 cur-rent limit with foldback and thermal limit with hysteresis. The LT3015 regulators are available in fixed output volt-ages of , 3V, , 5V, 12V and 15V and as an adjustable device with a reference voltage.
