LT3008 series is micropower, low dropout voltage (LDO) linear regulator. The devices supply 20mA output current with a dropout voltage of 300mV. 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 LT3008 regulators optimize stability and transient response with low ESR ceramic capacitors, requiring a minimum of only 2.2µF. 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 LT3008 series are ideal for applications that require moderate output drive capability coupled with ultralow standby power consumption. Suitable for use in automotive, low current battery-powered systems, keep alive power supplies, remote monitoring, utility meters and low power industrial applications.
