The Texas Instruments TPS71257DRCR is a dual-channel, low-dropout (LDO) linear voltage regulator designed for various applications. It operates with an input voltage range of 2.7V to 5.5V and provides a stable output current of up to 250mA per channel. This regulator is characterized by its ultra-low noise of 32 µVrms and high Power Supply Rejection Ratio (PSRR) of 65 dB at 10 kHz, making it suitable for sensitive analog circuits.
The TPS71257DRCR features independent enable pins for flexible control and includes protection features such as over-temperature, reverse polarity, and under-voltage lockout (UVLO). It is available in a compact 10-VSON (3x3 mm) package, suitable for surface mount applications where space is limited. The device supports fixed output voltage options including 1.8V, 2.8V, and 2.85V, as well as adjustable output configurations.
Key electrical specifications include a typical dropout voltage of 125mV at 250mA and a quiescent current of 0.3mA. The regulator is stable with a minimum load capacitance of 2.2µF. Its operating temperature range is -40°C to 125°C, ensuring reliable performance in demanding environments. Applications include cellular phones, wireless PDAs, digital cameras, and DSP/FPGA systems.
