STMicroelectronics Voltage Regulators - Linear LDL112DR

The LDL112DR is a low-dropout linear voltage regulator capable of delivering up to 1.2 A of output current. It operates with an input voltage range of 1.6 to 5.5 V and features a typical dropout voltage of 300 mV at a 1 A load. The device is designed with a very low quiescent current of 35 ¬µA at no load and can achieve less than 1 ¬µA in shutdown mode, making it suitable for battery-powered applications. This regulator offers an output voltage tolerance of ¬± 2.0% at 25 ¬8C and is compatible with ceramic capacitors as low as 1 ¬µF for output stabilization. It includes features such as reverse current protection, internal current and thermal limiting, and an optional output discharge function. The LDL112DR is available in multiple package options, including DFN6 (2x2 mm), DFN6 (3x3 mm), SO8-batwing, and PPAK, and operates over a temperature range of -40 ¬8C to 125 ¬8C. This combination of features makes the LDL112DR a versatile choice for applications in consumer electronics, computers, and USB-powered devices.
