DESCRIPTION

Low Dropout Linear Regulator

linear regulator. The device supplies 20mA output current

with a dropout voltage of 300mV. No-load quiescent cur-

rent 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 regulator optimizes stability and transient

response with low ESR ceramic capacitors, requiring a

minimum of only 2.2μF. The LT3008 does 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 is ideal for applications that require moderate

output drive capability coupled with ultralow standby power

consumption. The device is available as an adjustable

device with an output voltage range down to the 600mV

reference. The LT3008 is available in the 6-lead DFN and

8-lead TSOT-23 packages.
