TPS73701DCQR Description


The TPS73701DCQR employs a sophisticated BiCMOS technology for high precision and low ground pin current. When not activated, current consumption is less than 20 nA, making it perfect for portable use. Thermal shutdown and foldback current limit provide protection for these devices.

Consider using TI's TPS73701DCQR 1 percent overall accuracy, 1-A low-dropout voltage regulators for applications that require higher output voltage accuracy.
