Overview
The LT1767EMS8E-5#PBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 25 V and provides a fixed output voltage of 5 V. The device supports an output current of 1.2 A and integrates a high-efficiency 1.5 A switch. It functions at a switching frequency of 1.25 MHz using current mode control for stability. The component is housed in an MSOP-EP-8 package, features a shutdown pin, and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a high-efficiency 1.5 A power switch and complete current mode control circuitry on a single die.
- Provides fast transient response and excellent loop stability through high-frequency operation.
- Includes a dedicated shutdown pin for power management and extended battery life in portable applications.
Applications
- Battery-powered systems requiring efficient voltage regulation
- Portable instrumentation and measurement devices
- Industrial control systems with 5 V logic requirements
Procurement Notes
Verify the specific suffix #PBF indicates tube packaging versus TRPBF for reel packaging when ordering. Confirm RoHS compliance status and lead times directly with Analog Devices or authorized distributors, as availability may vary. Ensure the MSOP-EP-8 footprint matches the design layout before finalizing procurement.
Selection Notes
Select this part for designs requiring a fixed 5 V output from a 3 V to 25 V input source. The 1.25 MHz frequency allows for smaller external passive components compared to lower-frequency regulators. Consider the thermal performance of the exposed pad MSOP package for heat dissipation in compact enclosures.
Part Context
This component belongs to the LT1767 series of monolithic step-down switching regulators. The series includes variants with different fixed output voltages such as 1.8 V, 2.5 V, and 3.3 V. All members share the same core architecture, switching frequency, and package options, differing primarily in their internal feedback resistor networks.
Replacement Considerations
LT1767EMS8-5#TRPBF: Identical electrical specifications but supplied in tape and reel packaging instead of tubes. LT1767EMS8E-5#TRPBF: Same functional parameters with reel packaging; verify if the 'E' suffix denotes specific environmental or material changes per the manufacturer's documentation.
