Designedforuseinbattery-poweredsystems,thelow30μA  
quiescent current per output makes it an ideal choice. In  
shutdown, quiescent current drops to less than 0.1μA.  
Shutdowncontrolisindependentforeachoutput,allowing  
for flexibility in power management. The device is capable  
ofoperatingoveraninputvoltagerangeof1.8Vto20V.The  
device can supply 100mA of output current from Output  
2 with a dropout voltage of 300mV. Output 1 can supply  
500mA of output current with a dropout voltage of 300mV.  
Quiescent current is well controlled in dropout.  
Very Low Shutdown Current: <0.1μA  
Low Dropout Voltage: 300mV at 100mA/500mA

Thermally Enhanced 16-Lead TSSOP and 12-Lead  
(4mm × 3mm) DFN Packages  
The LT3024 regulator is stable with output capacitors as  
low as 1μF for the 100mA output and 3.3μF for the 500mA  
output. Small ceramic capacitors can be used without the  
series resistance required by other regulators.  
APPLICATIONS  
Internal protection circuitry includes reverse-battery  
protection, current limiting, thermal limiting and reverse  
current protection. The device is available as an adjust-  
able device with a 1.22V reference voltage. The LT3024  
regulator is available in the thermally enhanced 16-lead  
TSSOP and 12-lead, low profile (4mm × 3mm × 0.75mm)  
DFN packages.
