LT3024

The LT
®
3024 is a dual, micropower, low noise, low dropout
regulator. With an external 0.01μF bypass capacitor, output
noise drops to 20μV
RMS
over a 10Hz to 100kHz bandwidth.
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 fl exibility 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 profi le (4mm × 3mm × 0.75mm)
DFN packages.
