Description

The AP138 is a positive voltage linear regulator utilizing CMOS technology. The features that include low quiescent current (30A typ.), low dropout voltage, and high output voltage accuracy,make it ideal for battery applications. EN input connected to CMOS has low bias current. The space-saving SOT23-5L package is attractive for "Pocket" and "Hand Held" applications.

AP138 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 1000pF capacitor is necessary to be placed in between Bypass and Ground.

The AP138 is stable with a low ESR output capacitor of 1.0F or greater.
