LDLN025PU33R ST LDO Regulator | 4-DFN(1x1) | 3.3V Output, 250mA

Product Overview

The LDLN025PU33R from STMicroelectronics is a high-performance, low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It delivers a fixed output voltage of 3.3V with a maximum output current of 250mA. Housed in a compact 4-DFN (1x1 mm) package, this device offers excellent line and load regulation, making it ideal for noise-sensitive circuits. The LDLN025PU33R features a low quiescent current of 25 µA (typical) and a dropout voltage of only 200 mV at full load, ensuring efficient operation even with small input-output voltage differentials.
