Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575HVT-3.3

LM2575HVT-3.3

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575HVT-3.3 is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, delivering a fixed 3.3V output at up to 1A. It operates with an input voltage range of 4V to 60V and features a 52kHz internal oscillator. The device utilizes a TO-220-5 through-hole package for thermal management. Key electrical parameters include ±4% output voltage tolerance, 5mA quiescent current, and operation across a -40°C to +125°C temperature range.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-frequency switching regulator requiring minimal external components
Built-in thermal shutdown and cycle-by-cycle current limiting protection
TTL shutdown capability for low-power standby modes

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power systems
Pre-regulator circuits for switching regulators
Direct battery regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'LF' or 'NOPB' against the datasheet to confirm RoHS compliance status. Confirm that the TO-220-5 package matches the required PCB footprint. Ensure the fixed 3.3V output aligns with the target load requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required with high input voltages up to 60V. The TO-220-5 package supports through-hole mounting and provides adequate thermal dissipation for 1A loads without additional heatsinks in many applications. Consider the LM2575HVS series if surface-mount packaging is preferred.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575HV family of SIMPLE SWITCHER regulators. It serves as a high-efficiency alternative to linear regulators, significantly reducing heat generation. The family includes adjustable and other fixed voltage variants, all sharing the same core control architecture and protection features.
