The Texas Instruments TPS70448PWPR is a dual-channel, ultra-low-dropout (LDO) linear voltage regulator designed for split-supply applications. This device provides fixed output voltages of 3.3V for one regulator and 1.5V for the second, with output current capabilities of 1A and 2A respectively.
Key electrical features include a low quiescent current of 185µA typical and standby current of 2µA. It boasts fast transient response and low noise performance of 78µV RMS without a bypass capacitor. The regulator includes independent enable functions, power good outputs for both regulators, and a power-on reset with a 120ms delay.
Packaged in a 24-pin HTSSOP (PowerPAD), the TPS70448PWPR is suitable for surface mount applications. Its operating temperature range is -40°C to 125°C, making it robust for various environmental conditions. Protection features include over current, over temperature, reverse polarity, and undervoltage lockout (UVLO).
This LDO is well-suited for power management in systems requiring multiple, stable voltage rails. Its integrated features simplify design and reduce component count.
