Texas Instruments Voltage Regulators - Linear LM338KSTEEL

The LM338KSTEEL is a linear voltage regulator capable of delivering up to 5A of output current with an adjustable output voltage range from 1.2V to 32V. It features excellent load and line regulation, comparable to commercial power supplies, and is designed for ease of use with only two resistors required to set the output voltage. The device includes time-dependent current limiting, allowing for peak currents of up to 12A for short durations, making it suitable for applications with heavy transient loads. Additionally, it incorporates thermal overload protection and safe area protection for the power transistor, ensuring reliable operation even under fault conditions. The LM338KSTEEL is packaged in a standard Steel TO-3 package and operates within a temperature range of 0¬8C to +125¬8C. It is suitable for various applications, including adjustable power supplies, constant current regulators, and battery chargers. The regulator does not typically require external capacitors unless located far from input filter capacitors, although an output capacitor can enhance transient response.
