LINEAR TECHNOLOGY  LT3015IT  电压稳压器, LDO, 可调, -30V至-1.9V输入, 410mV压差, -1.22V至-29.5V/1.5A输出, TO-220-5

The is a 1.5A Negative Linear Regulator with precision current limit and 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 it ideal for noise sensitive applications. The LT3015 regulator is 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 fold back and thermal limit with hysteresis. The LT3015 regulator is available in fixed output voltages of -2.5, -3, -3.3, -5, -12 and -15V and as an adjustable device with a -1.22V reference voltage.
