3 Description
The TPS7A60-Q1 and TPS7A61-Q1 comprise 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 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. 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.
