Applications
The LT1767EMS8E-5 is used in point-of-load power conversion for portable instruments, industrial sensors, and embedded systems requiring an efficient 5 V rail from a higher input bus ranging from automotive 12 V down to 3 V near a depleted battery. Its 1.25 MHz switching frequency allows small surface-mount inductors and ceramic capacitors to be used, resulting in a very compact power module footprint.

Frequently Asked Questions
How wide is the input voltage range of the LT1767EMS8E-5, and can it step down from a 12 V automotive rail?
The LT1767EMS8E-5 accepts input voltages from 3 V to 25 V, comfortably covering a nominal 12 V automotive rail and even tolerant of 24 V industrial bus voltages. This makes it suitable for regulating a 5 V supply in vehicle electronics, industrial PLCs, and portable instruments powered from vehicle cigarette-lighter sockets.
What switching frequency does the LT1767EMS8E-5 use, and how does that influence inductor and capacitor selection?
The device switches at a fixed 1.25 MHz, enabling inductor values as small as 2.2 µH to 10 µH and output capacitors of 22 µF to 47 µF to be used without excessive ripple. Switching at 1.25 MHz also pushes ripple noise well above the audio band, which benefits audio and precision measurement applications.
Can LT1767EMS8E-5#PBF be used in a lead-free assembly process despite its Non-Pbfree code shown in some records?
The #PBF suffix in the MPN designates the RoHS-compliant, lead-free variant of the LT1767EMS8E-5, meaning the package uses a tin-based lead-free terminal finish compatible with standard 260°C peak reflow soldering profiles used in modern SMT assembly lines.
What is the maximum continuous load current for LT1767EMS8E-5 and how small is the package it fits in?
The regulator is rated for 1.5 A continuous output current delivered from an 8-pin MSOP package, which has a body footprint of roughly 3 mm × 3 mm. This current density makes it a competitive choice for space-constrained designs that need to power a 5 V sub-system from a higher-voltage bus.
