The LT ? 3008 series are micropower, low dropout voltage
(LDO) linear regulators. 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
