Lead-free
• Very Low Dropout Voltage
• Low Current Consumption: Typ. 45μA, max. 60uA
• 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)
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.
