LDO with low quiescent current of 3uA

Linear Technology's LT3008 features low quiescent current of 3uA. The LT3008 has high input voltage capability, spanning 2.0V to 45V with an adjustable output voltage ranging from 0.6V to 36V. The IC delivers up to 20mA output current with a corresponding low dropout voltage of only 300mV. Output tolerance is tightly regulated to within ±2% over line, load and temperature. The device's ultra low quiescent and shutdown makes it right choice for remote monitoring and low-current battery-powered memory for "keep alive" systems that require extended run times.

The LT3008 regulator optimizes stability and transient response with low ESR, ceramic output capacitors of 2.2uF. Internal protection circuitry includes reverse-battery protection; reverse output and reverse output-to-input protection, current limiting, and thermal limiting.
