Features - - - - - - - - - - - - Very Low Dropout Voltage Low Current Consumption: Typ. 45µA, max. 60m A Output Voltage: 1.5V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V 3.3V, and 3.5V Guaranteed 300m A Output Input Range from 2.7 up to 5.5V Thermal Shutdown Current Limiting Stability with Low ESR Capacitors Low Temperature Coefficient Lead-free Package: SOT25 SOT25: Available in “Green” Molding pound (No Br, Sb) Lead Free Finish/Ro HS pliant (Note 1) General Description The AP139 is a positive voltage linear regulator utilizing CMOS technology. The features that include low quiescent current (45µA typ.), 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. The space-saving SOT25 package is attractive for “pocket” and “hand held” applications. 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 10n F capacitor is necessary to be placed in between Bypass and Ground. The AP139 is stable with a low ESR output capacitor of 1.0µF or greater.
