Overview
The LE50CZ is a Low Dropout (LDO) Voltage Regulator produced by STMicroelectronics. It is designed to provide a stable output voltage of 5.0V with a maximum current of 100mA. This regulator operates as a positive regulator, increasing the input voltage to maintain the desired output voltage. The LE50CZ is available in two package options: TO-226-3 and TO-92-3 (also referred to as TO-226AA). Its compact design and high power efficiency make it suitable for various applications, particularly those requiring low-voltage supply and energy efficiency, such as battery-powered or energy-conscious designs.
