What are the key features of LT1965IMS8E-1.8#PBF?
- Fixed 1.8V output with 1.1A continuous current and only 310mV typical dropout voltage suits low-headroom automotive power rails
- AEC-Q100 automotive qualification and 2.8V to 20V input range cover a wide range of 12V vehicular and industrial supply conditions
- 8-pin MSOP with exposed pad (EP) enables compact PCB footprint with enhanced thermal dissipation without a large heatsink
What is LT1965IMS8E-1.8#PBF used for?
The LT1965IMS8E-1.8 is designed for automotive ECU subsystems and ADAS modules that require a stable, low-noise 1.8V rail from a 12V car battery or boost converter, where the low 310mV dropout voltage maximizes efficiency near end-of-charge battery conditions. Its 1.1A output current comfortably powers microcontrollers, FPGAs, and DSP cores operating at 1.8V supply rails in space-constrained control modules. Industrial designs such as 24V bus-powered sensor nodes and fieldbus interfaces also benefit from the wide 20V input tolerance and automotive-grade reliability.

Frequently Asked Questions
How low is the dropout voltage of the LT1965IMS8E-1.8 and why does it matter for 12V automotive designs?
The LT1965IMS8E-1.8 has a typical dropout voltage of 310mV at 1.1A, with a maximum of 490mV. In a 12V automotive system stepping down through multiple rails, a low dropout allows the regulator to maintain a clean 1.8V output even when the upstream supply sags to near 2.1V during cold-crank or load-dump events.
What input voltage range can the LT1965IMS8E-1.8 handle across automotive and industrial supply conditions?
The device accepts input voltages from 2.8V minimum up to 20V maximum, with an absolute maximum rating of 22V. This wide range covers standard 12V automotive batteries, boosted 15V rails, and 24V industrial bus supplies stepped down through a pre-regulator stage.
For a compact ADAS sensor board, how does the 8-pin MSOP EP package help manage thermal dissipation at full load?
At 1.1A output from a 5V input to 1.8V output, the LT1965IMS8E-1.8 dissipates approximately 3.6W. The exposed pad on the MSOP-8 EP package transfers heat directly to the PCB copper plane, achieving a junction-to-board thermal resistance that keeps the die below its 125°C maximum with adequate copper fill, without requiring a discrete heatsink.
Is the LT1965IMS8E-1.8 a suitable alternative to the LT1963 when pin count and output current requirements are similar?
Yes. Both devices deliver over 1A from a low-dropout architecture. The LT1965 series offers the automotive-grade qualification and MSOP-8 EP packaging that the standard LT1963 in SOT-223 does not provide, making LT1965IMS8E-1.8 the preferred choice when AEC-Q100 compliance or the smaller 8-pin MSOP footprint is a design requirement.
