The LM138K STEEL is a type of voltage regulator made by Linear Technology. It is a power integrated circuit designed to provide an adjustable constant output voltage using a simple two-pin input setup. It is rated to handle up to 50 Watts of continuous power making it suitable for a wide range of applications.
Overview
The LM138K STEEL is a low-dropout (LDO) voltage regulator with a wide input voltage range and a low quiescent current. The Large input voltage range of 4.75 V to 30 V makes it suitable for a variety of applications such as automotive, industrial, computing, and consumer electronic products. It also offers a low quiescent current of 1.8 mA and low-noise operation. The small 3 mm x 3 mm package with a basic two-pin input setup makes it suitable for space-constrained designs. The LM138K STEEL offers excellent line and load regulation and has a low temperature coefficient.

Working Principle
The LM138K STEEL is a low-dropout (LDO) voltage regulator that incorporates an adjustable current limit and thermal shutdown protection. It operates by sensing the input voltage and controlling the power transistor so that an adjustable voltage is maintained at the output. The current limit can be adjusted by an external resistor, while the thermal shutdown operates when the junction temperature reaches 175°C. The LM138K STEEL incorporates an open collector output which means that the regulator can be disabled by simply grounding the output.
The input voltage range and output voltage of the LM138K STEEL are adjustable independently and the output voltage can be set as a multiple of the input voltage. This feature allows the regulator to be used in applications where a constant voltage output is required, such as in battery management systems where the output voltage needs to be maintained even when the input voltage is varied.
The LM138K STEEL has excellent line and load regulation and is suitable for a wide range of applications in automotive, industrial, computing, and consumer electronic products. It is also suitable for applications in battery management systems, cellular and mobile phone power management systems, medical instrumentation, portable and/or hand-held electronic devices, adjustable voltage and current applications and telecommunication systems.
