Description

General part information

LT3009 Series

The LT3009 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 transient response with low ESR ceramic capacitors, requiring a minimum of only 1μF. 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 protection and reverse-current protection.The LT3009 Series are ideal for applications that require moderate output drive capability coupled with ultralow standby power consumption. The device is available in fixed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V, and as an adjustable device with an output voltage range down to the 600mV reference. The LT3009 is available in the 6-lead DFN and 8-lead SC70 packages.ApplicationsLow Current Battery-Powered SystemsKeep-Alive Power SuppliesRemote MonitoringUtility MetersHotel Door Locks
