The devices supply 20mA output current with a dropout voltage of 300mV. No-load quiescent current is 3µA. Ground pin current remains at less than 5% of output current as load increases. In shutdown, quiescent current is less than 1µA. The LT3007 regulators optimize stability and transient response with low ESR ceramic capacitors, requiring a minimum of only 2.2µF. The regulators do not require the addition of ESR as is common with other regulators. Internal protection circuitry includes current limiting, thermal limiting, reverse-battery ...
