Product Overview
The TLV70025DDCT from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. It delivers a fixed output voltage of 2.5V with a maximum output current of 200mA. The device is housed in a thin SOT-23 (SOT-23-THIN) package, making it ideal for portable and battery-powered electronics where board space is at a premium. With a low dropout voltage of typically 175mV at full load and a quiescent current of only 30µA, the TLV70025DDCT offers excellent efficiency and extends battery life in standby and active modes.
