DESCRIPTION
The TPS7A60xx/TPS7A61xx is a series 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 an integrated over current protection and are
designed to achieve stable operation even with low-
ESR ceramic capacitors. Power-On Reset delay is
implemented during device start up to indicate that
the output voltage is stable and in regulation. The
Power-On Reset delay is fixed (250 µs typical), and
can also be programmed by an external capacitor.
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.
