LT3015EQ-2.5#PBF

LT3015EQ-2.5#PBF LT®3015 series low noise, low dropout, negative linear regulator with fast transient response. This device can supply up to 1.5A of output current with a typical dropout voltage of 310mV. Its operating quiescent current is typically 1.1mA and drops to less than 1µA in shutdown. Quiescent current is also well-controlled during dropout. In addition to its fast transient response, the LT3015 series exhibits very low output noise, making it ideal for noise-sensitive applications. This regulator remains stable with a minimum 10µF output capacitor. Furthermore, it can utilize small ceramic capacitors without the need for additional equivalent series resistance (ESR), as required by many other regulators. Applications include post-regulator for switching supplies, negative logic supplies, low noise instrumentation, industrial supplies, negative complement to the LT1963A.
