regulator. With an external 0.01μF bypass capacitor, output

Designed for use in battery-powered systems, the low 30μA

quiescent current per output makes it an ideal choice. In

shutdown, quiescent current drops to less than 0.1μA.

Shutdown control is independent for each output, allowing

for flexibility in power management. The device is capable

of operating over an input voltage range of 1.8V to 20V. 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.

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.

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.
