LM140LAH-15

Overview

The LM140LAH-15 is a three-terminal positive linear voltage regulator from the LM140L series, manufactured by Texas Instruments. It provides a fixed output voltage of 15 V with a maximum output current capability of 100 mA. The device operates within an extended temperature range from -55 °C to +125 °C and features a typical power supply rejection ratio (PSRR) of 52 dB at 120 Hz. Electrical specifications include a line regulation of 0.04 %/V and a load regulation of 0.01 %/mA. The quiescent current is specified at 4.5 mA. It is housed in a TO-39-3 through-hole package.

Feature Summary

Provides a stable fixed positive output voltage suitable for precision applications
Operates reliably across an extended industrial temperature range
Features low quiescent current consumption for efficiency

Applications

Precision analog circuit power supplies
Test and measurement equipment
Industrial control systems requiring stable reference voltages

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with design requirements. Confirm that the TO-39-3 package dimensions match the target PCB layout. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure thermal management strategies account for the package's heat dissipation characteristics under expected load conditions.

Selection Notes

Select this component when a fixed 15 V output is required with moderate current demands up to 100 mA. Consider the LM140K series if higher current capacity near 1 A is necessary. Evaluate the thermal resistance of the TO-39-3 package relative to the expected power dissipation. Verify input voltage headroom to maintain proper regulation without excessive heat generation.

Part Context

This part belongs to the LM140 family of three-terminal positive regulators. The 'L' suffix typically denotes a lower current variant compared to standard versions. The 'AH' indicates the specific package style and temperature rating. This series serves as a foundational component for basic linear regulation tasks in electronic designs.
