TPS71257DRCT Description

Short technical summary and product information.

The Texas Instruments TPS71257DRCT is a dual-channel, low-dropout (LDO) linear voltage regulator tailored for noise-sensitive and RF applications. It offers ultralow noise, a high power-supply rejection ratio (PSRR), and fast transient and start-up response.

 

Key electrical specifications include a fixed output voltage of 2.85V, a maximum output current of 250mA per channel, and a low dropout voltage of 125mV at 250mA. The device features independent enable pins, thermal shutdown, and independent current limiting for robust operation. Its high PSRR of 65 dB at 10 kHz and ultralow noise of 32 µVrms make it suitable for demanding applications.

 

This regulator is available in a 10-VSON (3x3) package, suitable for surface mounting. The operating temperature range is -40°C to 125°C. Applications include cellular phones, wireless PDAs, PCMCIA/wireless LAN, digital cameras, and DSP/FPGA systems.
