LT3008IDC-3.3#TRMPBF

LT3008IDC-3.3#TRMPBF is a LT®3008 series micropower, low dropout voltage (LDO) linear regulator. It supplies 20mA of output current with a dropout voltage of 300mV. Its no-load quiescent current is merely 3μA, and the ground pin current remains below 5% of the output current as the load increases. During shutdown, the quiescent current drops to less than 1μA. This regulator optimizes stability and transient response with low ESR ceramic capacitors, requiring a minimum of only 2.2μF; device does not necessitate 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. Ideal for applications that require moderate output drive capability coupled with ultralow standby power consumption. Applications include automotive, low current battery-powered systems, keep-alive power supplies, remote monitoring, utility meters, and low power industrial applications.
