LT3009 - Linear Technology

LT3009 20mA Low Dropout Linear Regulators

The LT®3009 Series are micropower, low dropout voltage (LDO) linear regulators. The devices supply 20mA output current with a dropout voltage of 280mV. 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 LT3009 regulators optimize stability and .
