Description

General part information

LT3015 Series Series

The LT3015 series are low noise, low dropout, negative linear regulators with fast transient response. The devices supply up to 1.5A of output current at a typical dropout voltage of 310mV. Operating quiescent current is typically 1.1mA and drops to <1μA in shutdown. 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.The LT3015 regulators are available in fixed output voltages of –2.5V, –3V, –3.3V, –5V, –12V and –15V and as an adjustable device with a –1.22V reference voltage. Packages include the 5-lead TO-220 and DD-Pak, a thermally enhanced 12-lead MSOP and the low profile (0.75 mm) 8-lead 3mm × 3mm DFN.ApplicationsPost-Regulator for Switching SuppliesNegative Logic SuppliesLow Noise InstrumentationIndustrial SuppliesNegative Complement to the LT1963A
