AP139-18WG-7

The AP139-18WG-7 is a 1.8V fixed output low-noise low-dropout (LDO) Linear Regulator utilizing CMOS technology. The features that include low quiescent current (45μA typical), low dropout voltage and high output voltage accuracy, make it ideal for battery applications. EN input connected to the device will produce a low bias current. This rugged device has both thermal shutdown and current limit protections to prevent device failure under the "worst" operating conditions. In a low noise, regulated supply application, a 10nF capacitor is necessary to be placed in between Bypass and Ground. The device is stable with a low ESR output capacitor of 1μF or greater.

• 45μA Typical low current consumption
