AP139
300mA LOW-NOISE CMOS LDO
Features
Very Low Dropout Voltage Low Current Consumption: Typ. 45µA, max. 60mA Output Voltage: 1.5V, 1.8V, 2.0V, 2.5V, 2.8V, 3.0V 3.3V, and 3.5V Guaranteed 300mA 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 Compound (No Br, Sb) Lead Free Finish/RoHS Compliant (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 10nF 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.
Applications
Personal Communication Devices Home Electric/Electronic Appliances PC Peripherals Battery-Powered Devices
