TPS7A2042PDBVR

TPS7A2042PDBVR Description

The TPS7A2042PDBVR is a high-performance, low-dropout linear voltage regulator designed for applications requiring a stable and efficient power supply. Manufactured by Texas Instruments, this regulator is part of the Power Management Integrated Circuits (PMIC) category and offers a fixed output voltage of 4.2V. It is designed to operate with a maximum input voltage of 6V and can deliver up to 300mA of output current. The regulator features a low dropout voltage of 0.145V at 300mA, ensuring efficient operation even at low input-to-output voltage differences.

With a quiescent current of only 15 µA, the TPS7A2042PDBVR is optimized for low-power applications, making it ideal for battery-powered devices and portable electronics. The regulator also offers excellent Power Supply Rejection Ratio (PSRR), ranging from 65dB at 100Hz to 40dB at 1MHz, which helps in minimizing noise and ripple in the output voltage.
