78L05 Information

General Description

The UMW 78L05 is a Linear Voltage Regulator IC from the 78Lxx series. This positive fixed voltage regulator is designed to provide a stable output voltage of 1.7V with a maximum current of 100mA. The device features over current, over temperature, and short circuit protection, making it suitable for various applications such as power supply systems, audio equipment, and automotive electronics. The IC operates from an input voltage range of up to 30V and has a low dropout voltage of 1.7V @ 40mA. With a high power supply rejection ratio (PSRR) of 49dB at 120Hz, it effectively eliminates noise and ripple from the output. The 78L05 is available in a surface-mountable TO-243AA package with tape and reel, cut tape, or Digi-Reel packaging options.
