Linear debuts 45V LDO with 3?A IQ

Linear Technology has recently rolled out the latest member of its high voltage, micropower, robust PNP-based LDO family. The LT3007 features an ultra low 3?A quiescent current. Its high input voltage capability, which spans 2.0V to 45V with an adjustable output voltage ranging from 0.6V to 44.5V, enables operation in a wide variety of application spaces.

The LDO's pinout is Failure Mode Effects Analysis (FMEA) compliant—the output stays at or below the regulation voltage during an adjacent pin short event, or if a pin is left floating. The device's 3?A quiescent and shutdown (The device delivers up to 20mA output current with a corresponding low dropout voltage of only 300mV. Output voltage tolerance is tightly regulated to within ±2 per cent over line, load and temperature. The IC optimises stability and transient response with low ESR, ceramic output capacitors as small as 2.2?F. Internal protection circuitry includes reverse-battery protection, reverse output and reverse output-to-input protection, current limiting and thermal limiting for robustness.

The LT3007 is offered in both E and I grades in an 8-lead SOT-23 package with 3 pins fused to the ground paddle for enhanced thermal performance in both fixed and adjustable versions. 1,000-piece pricing starts at $1.20 each for the E grade.
