LT1933ES6#TRPBF

Overview

The LT1933ES6#TRPBF is a micropower step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6V to 36V and provides a maximum output current of 600mA. The device features a fixed switching frequency of 500kHz and delivers adjustable output voltages down to 1.25V. It utilizes a TSOT-23-6 package and supports a shutdown current of less than 2μA for efficient power management in battery-powered applications.

Feature Summary

Integrates a 0.75A internal power switch within a compact 6-lead SOT-23 package
Provides cycle-by-cycle current limit protection against shorted outputs
Includes soft-start functionality to eliminate input current surge during startup
Enables easy power management through low current shutdown mode

Applications

Regulating power from unregulated wall transformers
Powering systems from 24V industrial supplies
Battery-powered equipment requiring low quiescent current
Automotive battery supply regulation

Procurement Notes

Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm the specific ES6 suffix indicates the TSOT-23-6 package variant. Check RoHS compliance status as indicated in the datasheet. Ensure storage conditions align with manufacturer recommendations for surface-mount devices. Validate that the part number matches the exact specification required for the target circuit design.

Selection Notes

Select this regulator when a wide input voltage range up to 36V is required alongside a small form factor. It is suitable for designs needing moderate output currents up to 600mA without external pass transistors. Consider the 500kHz frequency for balancing inductor size and efficiency. Evaluate thermal performance based on the expected load and ambient temperature within the TSOT-23-6 footprint constraints.

Part Context

This component belongs to the LT1933 series of step-down DC/DC converters. It is designed for applications demanding high efficiency and minimal external component count. The series offers various package options including DFN, providing flexibility for different PCB space requirements while maintaining consistent electrical performance characteristics across the family.
