DESCRIPTION
The TPS7A63xx-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.
