FEATURES

DESCRIPTION

•

Low Dropout Voltage

The TPS7A60xx/TPS7A61xx is a series of low

–

dropout linear voltage regulators designed for low

•

4-V to 40-V Wide Input Voltage Range

power consumption and quiescent current less than

With up to 45-V Transients

25 µA in light load applications. These devices

feature an integrated over current protection and are

•

300-mA Maximum Output Current

designed to achieve stable operation even with low-

•

Ultra Low Quiescent Current

ESR ceramic capacitors. Power-On Reset delay is

–

implemented during device start up to indicate that

the output voltage is stable and in regulation. The

–

Power-On Reset delay is fixed (250 µs typical), and

•

3.3-V and 5-V Fixed Output Voltage

can also be programmed by an external capacitor.

•

Low-ESR Ceramic Output Stability Capacitor

Low voltage tracking feature allows for a smaller input

capacitor and can possibly eliminate the need of

•

Integrated Power-On Reset

using a boost converter during cold crank conditions.

–

Programmable Delay

Because of these features, these devices are well

–

Open-Drain Reset Output

suited in power supplies for various automotive

•

Integrated Fault Protection

applications.

–

Short-Circuit/Over-Current Protection

TYPICAL REGULATOR STABILITY

–

Thermal Shutdown

•

Low Input Voltage Tracking

•

Thermally Enhanced Power Package

–

5-pin TO-263 (KTT /D2PAK)

–
