DESCRIPTION
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
moderate output drive capability coupled with ultralow
standby power consumption. The device is available in
fixed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and
5V, and an adjustable version with an output voltage range
of 0.6V to 44.5V. The LT3008 is available in the thermally
enhanced 6-lead DFN and 8-lead TSOT-23 packages.
