LM237KCSE3

Overview

The LM237KCSE3 is a negative adjustable linear voltage regulator manufactured by Texas Instruments. It provides an output current of 1.5A with an input voltage range up to -40V and an adjustable output voltage from -1.2V to -37V. The device features a typical quiescent current of 10 mA and offers power supply rejection ratios ranging from 80dB to 65dB at 120Hz. It includes protection against overcurrent, thermal overload, and short circuits. The component operates within a temperature range of 0°C to 125°C and is housed in a TO-220-3 through-hole package.

Feature Summary

Negative adjustable regulation capability for stable power delivery
Integrated thermal overload and short-circuit protection mechanisms
Robust construction supporting high current loads

Applications

General-purpose negative power supply circuits
Industrial equipment requiring stable negative rails
Test and measurement instrumentation power systems

Procurement Notes

Verify the specific suffix 'CSE3' against official Texas Instruments documentation to confirm RoHS compliance and material composition details. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to avoid counterfeit components. Cross-reference the datasheet revision history for any recent manufacturing site changes that may affect performance specifications.

Selection Notes

Select this component when a reliable negative adjustable voltage source is required for applications demanding up to 1.5A output current. Consider the TO-220-3 package for through-hole mounting requirements and adequate heat dissipation capabilities. Evaluate the thermal management needs based on the expected voltage drop and load current to ensure operation within the specified junction temperature limits.

Part Context

This part belongs to the LM237/LM337 family of negative adjustable regulators. It serves as the negative counterpart to the widely used LM317 positive regulator. The series is known for its reliability and ease of use in various analog and digital circuit designs requiring negative voltage supplies.
