What are the key features of LT3091HR#PBF?
- Adjustable negative output voltage from 0 V to -32 V with a single resistor, enabling flexible power rail design
- 1.5 A continuous output current with only 360 mV typical dropout voltage, maximizing efficiency in low-headroom applications
- Automotive-grade 8-pin DDPAK (D2PAK) package with exposed pad for superior thermal dissipation in harsh environments
- Stable with small ceramic output capacitors, simplifying PCB layout and reducing BOM cost
What is LT3091HR#PBF used for?
The LT3091HR#PBF is well-suited for automotive infotainment and ADAS power rails that require a clean, regulated negative supply. It is also used in industrial instrumentation and op-amp bias networks where a negative voltage rail down to -32 V at up to 1.5 A is needed. Its low dropout and thermal performance make it ideal for battery-powered systems with tight headroom constraints.

Frequently Asked Questions
What is the output voltage range and maximum current the LT3091HR#PBF can supply?
The LT3091HR#PBF provides an adjustable negative output voltage from 0 V to -32 V, with a maximum continuous output current of 1.5 A. The dropout voltage is typically 360 mV, making it suitable for low-headroom power supply designs in automotive and industrial applications.
Which automotive or industrial designs benefit most from the LT3091HR#PBF's DDPAK package?
The 8-pin DDPAK package with exposed thermal pad is ideal for automotive ECU power stages, motor-drive bias rails, and industrial amplifier supplies where up to 1.5 A at voltages down to -32 V must be delivered in a thermally demanding environment. The large pad reduces junction-to-board thermal resistance, enabling sustained operation without external heatsinks in many cases.
How does the LT3091HR#PBF compare to fixed negative LDO regulators in terms of design flexibility?
Unlike fixed-voltage negative regulators, the LT3091HR#PBF uses a single external resistor to set any output voltage between 0 V and -32 V, eliminating the need to stock multiple fixed-voltage SKUs. It also supports output current sharing when multiple devices are paralleled, a capability uncommon in standard fixed LDOs, which is useful for delivering currents above 1.5 A in high-power designs.
Is the LT3091HR#PBF compliant with RoHS and automotive reliability standards?
The LT3091HR#PBF carries JESD-609 code e3, indicating it is a lead-free (Pb-free) part compatible with RoHS requirements. Its HR grade designation confirms it is rated for automotive-grade temperature ranges, making it compliant with the reliability expectations of AEC-Q100 class systems operating in environments from -40°C to 125°C.
