AX6607

600mA LDO Linear Regulator with Shutdown



GENERAL DESCRIPTION

The AX6607 is a low dropout, positive linear regulator with very low quiescent. It can

supply 600mA output current. The BP pin with a 10nF bypass capacitor can help reduce the

output noise level. The characteristics of low dropout voltage and less quiescent current

make it good for some critical current application, for example, some battery powered

devices. The typical quiescent current is approximately 50μA. In the shutdown mode, the

maximum supply current is less than 2μA. The AX6607 regulator is able to operate with

output capacitors as small as 1μF for stability. The AX6607 series are offering several fixed

output voltage types including 1.2V, 1.5V, 1.8V, 2.5V, 2.6V, 2.7V, 2.8V, 3.0V, 3.3V and

adjustable version. Built-in current-limit and thermal-shutdown functions prevent any fault

condition from IC damage.
