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.
