LDL212DR ST LDO Regulator | 8-SO | 1.2A, 0.3V Dropout

Product Overview

The LDL212DR is a high-performance low-dropout (LDO) linear voltage regulator from STMicroelectronics, designed for applications requiring low quiescent current, high output current capability, and excellent transient response. Housed in an 8-SO package, this device delivers up to 1.2A output current with a dropout voltage as low as 0.3V at full load. It features a wide input voltage range from 2.5V to 18V and provides a fixed or adjustable output voltage from 0.8V to 5.5V. The LDL212DR integrates protection features such as overcurrent, overtemperature, and reverse current protection, making it suitable for demanding industrial, automotive, and consumer applications.
