FMEA compliant 45-V LDO enables ultralow standby power consumption
The LT3007’s high input voltage capability, spanning 2.0 V to 45 V with an adjustable output voltage ranging from 0.6 V to 44.5 V, enables operation in a wide variety of application spaces. The LT3007’s pinout is FMEA (Failure Mode Effects Analysis) 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 µA quiescent and shutdown (<1 µA) currents enable ultralow standby power consumption, making the IC an excellent choice for applications not needing shutdown, or those requiring moderate output drive capability and high input voltage, such as remote monitoring and low-current battery-powered memory for ‘keep alive’ systems that require extended run times.
The LT3007 delivers up to 20 mA output current with a corresponding low dropout voltage of 300 mV. 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 2.2 µF. Internal protection circuitry includes reverse-battery protection, reverse output and reverse output-to-input protection, current limiting and thermal limiting for robustness.
Pricing
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.
