The BCT2561ELS185-TR with UTDFN1x1-4L Linear Voltage Regulators (LDO) is a ROHS compliant integrated circuit (IC) device manufactured by BROADCHIP. It is a highly efficient, low-dropout (LDO), step-down switching regulator compatible with a wide input voltage range. This chip features a maximum output current of 1.2A, a low dropout voltage of 185 mV at full load (1.2A) and low quiescent current of 10 µA. The device also has an input voltage range of 2.3V to 6.0V and an adjustable output voltage range of 0.9V to 5V with an accuracy of ±2%. It also includes additional features like soft start, Brownout detection, output Overvoltage protection, undervoltage lockout, load current monitoring function, and thermal shutdown protection. This device is designed with a UTDFN1x1-4L packageB for surface mount applications and is a great choice for low power applications such as mobile phones and home automation systems.
