The 78L05MG-AB3-R is a linear voltage regulator (LVR) developed by Unisonic Technologies Corporation (UTC) in a small surface-mount package, known as a SOT-89-3 (Small Outline Transistor-89-3). It is a three-terminal, positive-voltage regulator designed to provide regulated 5V output form a supply voltage of up to 40V. It includes an internal temperature compensated reference and current limiting, making it an ideal choice for low voltage applications. The device is RoHS compliant and offers up to 500mA continuous output current with excellent line and load regulation. It is capable of operating over a temperature range of -40 to +125COMP_C, making it suitable for applications in a variety of different environments. Moreover, it can achieve a wide input voltage range of 4.5 to 40V and has an output voltage accuracy of ±2% over line, load and temperature changes.
