LT3008

The LT®3008 is a micropower, low dropout voltage (LDO) linear regulator. The device supplies 20mA output current with a dropout voltage of 300mV. No-load quiescent current is 3A. Ground pin current remains at less than 5% of output current as load increases. In shutdown, quiescent current is less than 1A.

The LT3008 regulator optimizes stability and transient response with low ESR ceramic capacitors, requiring a minimum of only 2.2F.

The LT3008 does not require the addition of ESR as is common with other regulators. Internal protection circuitry includes current limiting, thermal limiting, reverse-battery protection and reversecurrent protection. The LT3008 is ideal for applications that require moderate output drive capability coupled with ultralow standby power consumption.

The device is available as an adjustable device with an output voltage range down to the 600mV reference. The LT3008 is available in the 6-lead DFN and 8-lead TSOT-23 packages.
