LD2981ABM33TR ST LDO Regulator | SOT-23-5 | 3.3V Output, 100mA

Product Overview

The LD2981ABM33TR from STMicroelectronics is a low dropout voltage regulator (LDO) designed for applications requiring a stable 3.3V output voltage with up to 100mA output current. Housed in a compact SOT-23-5 package, it offers excellent line and load regulation, making it ideal for space-constrained designs. The device features a dropout voltage as low as 0.2V at 100mA, enabling efficient operation even with low input-to-output voltage differentials. Built-in protection circuits include thermal shutdown and current limiting, ensuring reliable performance under fault conditions.
