LT1933ES6#TRMPBF

Overview

The LT1933ES6#TRMPBF is a micropower step-down switching regulator manufactured by Analog Devices Inc., housed in a TSOT-23-6 package. It operates with an input voltage range of 3.6V to 36V and delivers up to 600mA output current. The device features a fixed 500kHz switching frequency, adjustable output voltage down to 1.25V, and a shutdown current below 2μA. It includes internal soft-start and cycle-by-cycle current limit protection.

Feature Summary

Integrates a 0.75A power switch for efficient step-down conversion
Provides low quiescent current operation suitable for battery-powered systems
Includes internal soft-start to eliminate input current surge during startup

Applications

Regulating power from unregulated wall transformers
Power management in 24V industrial supply systems
Automotive battery voltage regulation applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure the TSOT-23-6 package matches your PCB footprint design. Review datasheet revisions for any updates to electrical characteristics before finalizing procurement orders.

Selection Notes

Select this regulator when a wide input voltage range and compact SOT-23 packaging are required. The 500kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 600mA output limit and 1.25V minimum output voltage constraints. Evaluate thermal performance within the TSOT-23-6 package for your specific load conditions.

Part Context

This part belongs to the LT1933 series of micropower step-down DC/DC converters. It is designed for applications requiring high efficiency in small form factors. The ES6 suffix indicates the TSOT-23-6 package variant. The #TRMPBF designation specifies the tape and reel packaging format with lead-free composition.
