Description

ACE5172C is a series of low power consumption, low dropout voltage regulator with a typical dropout

voltage of 1.0V at 2A load current.

ACE5172C can provide output value in the range of 1.2V~5.0V in 0.1V steps. It also can customize on

command.

Other than every voltage version can be used as an adjustable voltage version, with which desired

voltage can be achieved by setting the values of two external resistors of the application circuitry.

ACE5172C has well load transient response and good temperature characteristic, and it uses trimming

technique to guarantee output voltage accuracy within±2%.

ACE5172C series is available in standard packages of SOT-223 and TO-252.
