Overview
The LT3505IMS8E#TRPBF is a step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6 V to 36 V and delivers a maximum output current of 1.2 A. The adjustable output voltage spans from 0.78 V to 33.84 V. The device features a programmable switching frequency between 200 kHz and 3 MHz. It incorporates a shutdown function and maintains a typical quiescent current of 2 mA. The component is housed in an 8-pin MSOP EP package and supports surface mount installation.
Feature Summary
- Integrates a high-voltage power switch for efficient buck conversion
- Supports wide input voltage ranges suitable for industrial applications
- Includes programmable switching frequency control for optimization
- Features a dedicated shutdown pin for power management
Applications
- Industrial point-of-load regulation
- Automotive electronics power systems
- Distributed power architectures
- Battery-powered equipment supply chains
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the MSOP-8EP package footprint matches the design requirements. Validate that the automotive grade designation aligns with project specifications before finalizing procurement orders.
Selection Notes
Select this component when a wide input voltage range up to 36 V is required. Choose this part for designs needing adjustable output voltages with a 1.2 A current capacity. Consider this regulator for applications requiring flexible switching frequency settings to minimize EMI or optimize efficiency. Verify thermal performance within the MSOP-8EP package constraints.
Part Context
This part belongs to the LT3505 series of high-voltage step-down switching regulators. The series is designed for robust performance in demanding environments. The IMS8E variant specifies the MSOP-8EP package type. The #TRPBF suffix denotes the specific reel packaging format provided by the manufacturer.
Replacement Considerations
LT3505EDD#PBF offers the same electrical specifications in a DFN-8EP tube package. LT3505IDD#TRPBF provides identical functionality in a DFN-8EP tape and reel format.
