Key Features
- Wide input voltage range of 2 V to 45 V with 50 V absolute maximum for automotive transient tolerance
- Ultra-low 300 mV typical dropout voltage at 20 mA output for efficient regulation from low headroom supplies
- Fixed 3.3 V output in a compact 6-pin DFN package enabling minimal PCB footprint in space-constrained designs
- Automotive-grade qualification supporting harsh under-hood and body electronics environments
Applications
The LT3008IDC-3.3 is ideal for automotive electronics such as body control modules, infotainment systems, and ADAS sensor boards where a stable 3.3 V logic rail must be derived from a 12 V or 24 V vehicle battery with voltage transients up to 50 V. Its low 300 mV dropout voltage makes it efficient when the battery discharges to near 3.6 V in cold-start conditions. The compact 6-pin DFN package is also well suited for industrial sensor nodes, wearables, and portable instruments powered from wide-range input sources.

Frequently Asked Questions
What is the dropout voltage of the LT3008IDC-3.3 at its rated output current, and why does this matter for automotive use?
The LT3008IDC-3.3 has a typical dropout voltage of 300 mV and a maximum of 500 mV at its 20 mA output current rating. In automotive applications where a 12 V battery can droop below 6 V during cold cranking, the low dropout ensures continuous 3.3 V regulation even when input voltage briefly approaches 3.8 V, protecting microcontrollers and sensors from under-voltage reset.
How wide is the input voltage range of the LT3008IDC-3.3, and can it handle automotive load-dump transients?
The LT3008IDC-3.3 accepts an input voltage from 2 V to 45 V in normal operation, with an absolute maximum of 50 V for brief transients. This 50 V transient capability is aligned with ISO 7637 automotive load-dump pulse requirements, allowing the regulator to survive the voltage spikes generated when inductive loads are suddenly disconnected from the vehicle's 12 V or 24 V battery system.
What advantages does the 6-pin DFN package offer for the LT3008IDC-3.3 in a compact board design?
The 6-pin DFN (2 mm × 2 mm) of the LT3008IDC-3.3 is approximately 75% smaller in PCB footprint than a standard SOT-23-5 or TO-252 LDO package, while the exposed thermal pad improves heat dissipation at 20 mA output current. This combination allows the regulator to be placed directly adjacent to the load IC in density-critical automotive or industrial sensor modules.
When is the LT3008IDC-3.3 a better choice than a switching regulator for a 3.3 V automotive rail?
The LT3008IDC-3.3 is preferred over a switching regulator when low EMI, simple design, and fast transient response are required at output currents of 20 mA or less, such as for powering a microcontroller or sensor from a 5 V or 12 V intermediate bus. Its linear topology eliminates switching noise that would require additional filtering in sensitive analog or RF circuits operating at 3.3 V within a 2 V to 45 V input range.
