3 Description

The TPS7A63-Q1 and TPS7A6401-Q1 are a family of

low-dropout linear voltage regulators designed for low

power consumption and quiescent current less than

35 µA in light-load applications. These devices,

designed to achieve stable operation even with a low

ESR ceramic output capacitor, feature an integrated

programmable window watchdog and overcurrent

protection. Designers can program the output voltage

using external resistors. 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. The power

on-reset delay is fixed (250 µs typical), or an external

capacitor can program the delay. Because of such

features, these devices are well-suited in power

supplies for various automotive applications.
