The TPS70748PWP from Texas Instruments is a dual-channel, low-dropout (LDO) voltage regulator designed for applications requiring split voltage rails, such as DSP systems, processors, ASICs, and FPGAs. This device provides two independent regulators, with Regulator 1 capable of supplying up to 250mA and Regulator 2 up to 125mA. It features selectable power-up sequencing, enabling precise control over the power-on timing of different voltage rails.
Key electrical characteristics include a low dropout voltage (typically 0.14V @ 250mA for Regulator 1), a wide operating temperature range of -40°C to 125°C, and a high Power Supply Rejection Ratio (PSRR) of 60dB at 1kHz. The device also includes essential protection features such as over current, over temperature, reverse polarity, and undervoltage lockout (UVLO).
Packaged in a 20-pin HTSSOP, the TPS70748PWP is suitable for surface-mount applications. Its design prioritizes low noise and fast transient response, making it a robust solution for power management in demanding digital systems. The inclusion of power good and reset signals further aids in system monitoring and control.
