TPS76901SHKJ

TPS76901SHKJ Description

The TPS76901SHKJ from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for precision power management in space-constrained applications. With an adjustable output range of 1.2V to 4.5V and a maximum input voltage of 10V, it delivers a stable 100mA output current while maintaining ultra-low quiescent current (28 µA). This regulator is ideal for battery-powered and portable devices, offering high efficiency and minimal power dissipation. Its surface-mount 8CFP package ensures compact integration, and its Last Time Buy status indicates limited availability, making it critical for legacy designs.
