The LT3008 is the newest member in a family of high voltage, micropower PNP-based LDOs. The LT3008 has high input voltage capability, spanning 2V to 45V with an adjustable output voltage ranging from 0.6V to 44.5V. The regulator 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 ultralow quiescent and shutdown (<1uA) currents make it an excellent choice for applications requiring moderate output drive capability and high input voltage, coupled with ultralow standby power consumption, such as remote monitoring and low-current battery-powered memory.
