300-mA 40-V LOW-DROPOUT REGULATOR WITH 25-µA QUIESCENT CURRENT

Check for Samples: TPS7A6533-Q1, TPS7A6550-Q1

FEATURES

DESCRIPTION

The TPS7A65xx-Q1 is a family of low-dropout linear

voltage regulators designed for low power

consumption and quiescent current less than 25 µA in

light-load applications. These devices feature

integrated overcurrent protection and a design to

achieve stable operation even with low-ESR ceramic

output capacitors. 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. Because of these features,

these devices are well-suited in power supplies for

various automotive applications.
