3uA IQ 20mA LDO in 2mm x 2mm DFN & SC-70
MILPITAS, CA – May 17, 2007 – Linear Technology Corporation announces the LT3009, a
micropower LDO with ultra-low quiescent current of just 3uA. The LT3009 features a low
dropout voltage of only 280mV and delivers up to 20mA of output current, with wide VIN
capability of 1.6V to 20V and an adjustable output from 0.6V to 19.5V. Output tolerance is
tightly regulated to within ±2% over line, load and temperature. The device’s ultra-low quiescent
and shutdown (<1uA) currents make it an excellent choice for applications requiring moderate
output drive capability coupled with ultra-low standby power consumption, such as remote
monitoring and low-current battery-powered memory for “keep alive” systems that require
extended run times.
The LT3009 regulator optimizes stability and transient response with low ESR, ceramic
output capacitors as small as 1uF. These tiny external capacitors can be used without any
necessary series resistance as is common with many other regulators. Internal protection circuitry
includes reverse-battery protection, reverse output and reverse output-to-input protection, current
limiting, and thermal limiting.
The LT3009EDC is housed in the low profile (0.75mm) 6-lead DFN (2mm x 2mm)
package, while the LT3009ESC8 is offered in the 8-lead SC-70 package. 1,000-piece pricing
starts at $0.95 for each.
