DESCRIPTION
The TPS7A66xx and TPS7A69xx 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 micro 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. These features suit the devices well for power
supplies in various automotive applications.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to GND
(3) Absolute negative voltage on these pins not to go below –0.3 V
(4) Absolute maximum voltage, withstand 45 V for 200 ms
(5) The human-body model is a 107-pF capacitor discharged through a 1.5-kΩ resistor into each pin.
