What are the key features of LT3061EMS8E-3.3#PBF?
- 45 V maximum input voltage (50 V absolute max) enables use in high-voltage industrial and automotive power supply rails
- 250 mV typical dropout voltage at 100 mA output current minimizes power dissipation in low-headroom applications
- Integrated output discharge function rapidly pulls the output to ground when the regulator is disabled, preventing load latch-up
What is LT3061EMS8E-3.3#PBF used for?
The LT3061EMS8E-3.3#PBF is ideally suited for industrial sensors, automotive electronics, and high-voltage measurement systems that require a clean, stable 3.3 V rail derived from a wide input voltage ranging from 3.9 V to 45 V. Its micropower quiescent current and low-noise output make it an excellent choice for powering precision ADCs, op-amps, and reference circuits in environments where supply transients and noise directly impact measurement accuracy.

Frequently Asked Questions
What input voltage range does the LT3061EMS8E-3.3#PBF support, and how does that benefit industrial designs?
The LT3061EMS8E-3.3#PBF operates from 3.9 V to 45 V input (with a 50 V absolute maximum), making it compatible with 12 V, 24 V, and 36 V industrial bus rails. This wide input range lets designers power a fixed 3.3 V logic or sensor rail directly from unregulated industrial supplies without an intermediate conversion stage, simplifying the power tree and reducing BOM cost.
How does the LT3061EMS8E-3.3's dropout voltage affect its usability near the output voltage?
With a typical dropout voltage of 250 mV (maximum 430 mV at 100 mA), the LT3061EMS8E-3.3 can maintain a regulated 3.3 V output from an input as low as 3.55 V under typical conditions. This low dropout characteristic is critical in battery-operated systems where supply voltage sags toward end-of-discharge, allowing the regulator to hold regulation with only 250 mV of headroom rather than the 1 V or more required by older LDO topologies.
Why does the integrated output discharge feature matter in sequenced power supply systems?
The integrated output discharge function actively pulls the 3.3 V output rail toward 0 V within milliseconds when the regulator is shut down. In multi-rail systems with strict power-up and power-down sequencing, this prevents the 3.3 V node from floating high after disable, which could back-power sensitive ICs through their I/O clamp diodes or delay re-initialization on the next power cycle.
What package does the LT3061EMS8E-3.3#PBF use, and is it suitable for high-density PCB layouts?
The LT3061EMS8E-3.3#PBF is housed in an MSOP-8E package (8 pins with exposed pad), which provides a compact footprint of approximately 3 mm × 3 mm. The exposed thermal pad improves heat dissipation compared to standard MSOP-8, allowing the device to handle continuous 100 mA output currents with lower junction temperature rise, making it suitable for thermally constrained high-density boards.
