TPS70348PWP

The Texas Instruments TPS70348PWP is a dual-channel, ultra-low-dropout linear voltage regulator. It is designed to provide a complete power management solution for applications requiring split voltage rails, such as TI DSP systems, processors, and digital applications. This device features independent enable functions, power good output for Regulator 1, and a power-on reset with a 120 ms delay.

Key electrical specifications include a maximum input voltage of 6V, and dual output voltages with fixed options like 3.3V/1.5V, 3.3V/1.8V, 3.3V/2.5V, and 3.3V/1.2V, as well as dual adjustable outputs. Regulator 1 supports up to 1A output current, while Regulator 2 supports up to 2A. The device boasts a low dropout voltage of 160 mV typical at 1A, low quiescent current of 185 µA typical, and low noise output of 78 µVrms without a bypass capacitor. It also includes features like over current, over temperature, reverse polarity, and undervoltage lockout protection.

The TPS70348PWP is supplied in a 24-pin HTSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C. The device integrates SVS supervisory circuits for power sequencing and includes manual reset inputs, making it ideal for systems with specific power-up requirements.
