FMEA Compliant, 45V LDO Features 3µA IQ with
H-Grade Temperature Range up to +150°C
MILPITAS, CA – December 11, 2014 – Linear Technology Corporation announces a new wider
temperature range, H grade version of the LT3007, the latest member in a family of high voltage,
micropower, robust PNP-based LDOs, featuring an ultralow 3µA quiescent current. The device’s
H grade 150°C junction temperature rating enables high temperature or high power automotive
and industrial applications. Its high input voltage capability, spanning 2.0V to 45V with an
adjustable output voltage ranging from 0.6V to 44.5V, enables operation in a wide range of
applications. The LT3007’s pinout is FMEA (Failure Mode Effects Analysis) compliant, so 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 3µA quiescent and shutdown currents (<1µA) enable ultralow standby
power consumption, making the IC ideal for applications not requiring shutdown, or those
needing moderate output drive capability and high input voltage, such as remote monitoring and
low-current battery-powered memory for “keep alive” systems requiring extended run times.
The LT3007 delivers up to 20mA output current with a corresponding low dropout
voltage of only 300mV. Output voltage tolerance is tightly regulated to within ±2% over line,
load and temperature. The IC optimizes stability and transient response with low ESR, ceramic
output capacitors as small as 2.2µF. 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 E, I and H 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 and 1.75 for the H grade. For
