Texas Instruments TLV70233DBVR LDO Voltage Regulator 3.3V 300mA SOT-23-5

The TLV70233DBVR from Texas Instruments is a fixed-output, low-dropout (LDO) linear regulator that delivers a stable 3.3V output with a maximum current of 300mA. Engineered for power-sensitive applications, this regulator features a low quiescent current of just 35µA, making it ideal for battery-powered portable devices that require extended operation times.

With a wide input voltage range of 2V to 5.5V and a typical dropout voltage of 260mV, this regulator ensures efficient operation even with low input margins. The device provides excellent line and load transient performance, maintaining 2% output accuracy thanks to its precision bandgap and error amplifier. A high PSRR of 68dB at 1kHz minimises noise from the power supply, while low output noise further enhances performance in sensitive applications.

The TLV70233DBVR includes essential protection features such as thermal shutdown and overcurrent protection, ensuring safe and reliable operation under fault conditions. It is stable with an effective output capacitance of only 0.1µF, allowing the use of capacitors with high bias voltages and temperature derating. This green product is free from antimony and bromine, complying with environmental standards.

Packaged in a compact SOT-23-5 surface-mount case, this regulator is suitable for a wide range of applications, from consumer electronics to wireless and networking equipment. Its low quiescent current and high performance make it a versatile choice for modern electronic designs.
