The Texas Instruments TPS70745PWP is a dual-channel low-dropout (LDO) linear voltage regulator designed for applications requiring split-supply voltage regulation. This device provides two output voltages, specifically fixed 3.3V and 1.2V, with Regulator 1 capable of supplying up to 250mA and Regulator 2 up to 125mA.
Key electrical characteristics include a low quiescent current of 190µA typical and an input current of 1µA during standby. It features fast transient response, a voltage dropout of 0.14V at 250mA, and a PSRR of 60dB at 1kHz. Protection features include over current, over temperature, reverse polarity, and undervoltage lockout (UVLO).
The TPS70745PWP is housed in a 20-pin HTSSOP package and supports surface mount installation. It operates within a temperature range of -40°C to 125°C. The device includes control features such as Enable, Power Good, Reset, and Sequencing, making it suitable for complex power management solutions.
