TLV743105PDBVR Description

Short technical summary and product information.

The Texas Instruments TLV743P series, including the TLV743105PDBVR, are ultra-small, low quiescent current linear voltage regulators (LDOs) designed for efficient power management. This specific part provides a fixed output voltage of 1.05V and can source up to 300mA.

 

Key electrical characteristics include a low dropout voltage of 122mV typical at 300mA, a typical quiescent current of 34µA, and high power supply rejection ratio (PSRR) of 28dB at 100 KHz. The device offers a typical accuracy of 1% and includes protection features such as current limit, thermal shutdown, and UVLO (Under-Voltage Lockout).

 

Designed for space-constrained applications, the TLV743105PDBVR is available in a SOT-23-5 package, requiring surface mount technology. It operates within a temperature range of -40°C to 125°C. The regulator is stable with a minimum load capacitance of 1µF ceramic output capacitor.
