LDL212PUR ST LDO Regulator | 6-DFN(3x3) | 1.2A, Adjustable Output

Product Overview

The LDL212PUR from STMicroelectronics is a high-performance low-dropout (LDO) linear voltage regulator designed for applications requiring low noise, high PSRR, and fast transient response. It delivers up to 1.2 A output current with a dropout voltage as low as 350 mV (typical) at full load. The device operates from an input voltage range of 1.8 V to 5.5 V, making it suitable for battery-powered and post-regulation applications. The output voltage is adjustable from 0.8 V to VIN - VDROP using an external resistor divider. The LDL212PUR is available in a compact 6-lead DFN (3x3 mm) package, offering excellent thermal performance.
