LT3008 - Linear Technology

LT3008 45V Low Dropout Linear Regulator

The LT®3008 series are micropower, low dropout voltage (LDO) linear regulators. 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.
