The TLV749 is a 3A low-dropout (LDO) linear regulator. The device converts a higher input voltage to a stable, lower output voltage with minimal noise, providing a robust, easy-to-use power management design for a wide variety of applications.
The TLV749 supports a 1.0V to 5.5V input voltage range and an adjustable output voltage range from 0.8V to 3.6V, making the device well-suited for Low-Input, Low-Output (LILO) applications that demand up to 3A of continuous output current. The ultra-low dropout voltage makes the device particularly good for applications where VOUT is very close to VIN, maximizing efficiency across multiple power rails and system architectures.
The active-high enable pin (EN) allows the device to be placed into shutdown to minimize power dissipation, while the power-good output (PG), which asserts when VOUT reaches 90% of the rated value, enables straightforward power sequencing with external regulators, accommodating applications with strict startup ordering requirements.
A precision bandgap reference and error amplifier deliver ±1.5% output voltage accuracy. The TLV749 is fully specified across a junction temperature range of –40°C to 125°C, providing reliable performance in industrial and high-temperature environments.
