3 Description
The TPS7A66-Q1 and TPS7A69-Q1 are low-dropout
linear regulators designed for up to 40-V Vin
operations. With only 12-µA quiescent current at no
load, they are quite suitable for standby
microprocessor control-unit systems, especially in
automotive applications.
The devices feature integrated short-circuit and
overcurrent protection. The devices implement reset
delay on power up to indicate the output voltage is
stable and in regulation. One can program the delay
with 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.
The devices operate in the –40°C to 125°C
temperature range. The TPS7A6650EDGNRQ1
device is qualified to AEC-Q100 grade 0, operating in
the –40°C to 150°C temperature range. These
features suit the devices well for power supplies in
various automotive applications.
