3 Description
The TPS7A65xx-Q1 is a family of low-dropout linear
voltage regulators designed for low power
consumption and quiescent current less than 25 µA in
light-load applications. These devices feature
integrated overcurrent protection and a design to
achieve stable operation even with low-ESR ceramic
output capacitors. A low-voltage tracking feature
allows for a smaller input capacitor and can possibly
eliminate the need of using a boost converter during
cold crank conditions. Because of these features,
these devices are well-suited in power supplies for
various automotive applications.
