LT3009ESC8#TRMPBF

LT3009 series is a micropower, low dropout voltage (LDO) linear regulator. The device 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. This regulator 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. This is ideal for applications that require moderate output drive capability coupled with ultralow standby power consumption. Typical applications are low current battery-powered systems, keep-alive power supplies, remote monitoring, utility meters, hotel door locks.
