The AP139-25WG-7 is a positive voltage linear regulator designed using CMOS technology, suitable for battery-powered applications due to its low quiescent current of 45OºA (typical) and low dropout voltage. It supports output voltages of 2.5V and is capable of delivering up to 300mA of output current. The input voltage range is from 2.7V to 5.5V, making it versatile for various applications. The device features thermal shutdown and current limiting protections to enhance reliability under adverse conditions. It is stable with low ESR output capacitors of 1.0OºF or greater and requires a 10nF capacitor for low noise applications. The AP139 is housed in a compact SOT25 package, making it suitable for space-constrained designs. However, it is important to note that the AP139 is not recommended for new designs, and users are advised to consider the AP7343 instead.
