ANALOG DEVICES LT3008ITS8-5#TRMPBF LDO Voltage Regulator, Fixed, 2 to 45V in, 300mV Drop, 5V / 0.02A Out, TSOT-23-8, -40 to 125 °C

LT3008ITS8-5#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 3?A, 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 1?A. This regulator optimizes stability and transient response with low ESR ceramic capacitors, requiring a minimum of only 2.2?F; 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.
