The AP2205 series is a positive voltage regulator IC fabricated by a high-voltage EPNP process.
The AP2205 has various features such as a wide input voltage range, high accuracy, high ripple rejection, low dropout voltage, low noise, current limit, and ultra-low quiescent current—which make it ideal for use in various USB and portable devices.
The IC consists of a voltage reference, an error amplifier, a resistor network for setting output voltage, a current limit circuit for current protection, a chip enable circuit, a low power shutdown mode for extended battery life, overcurrent protection, overtemperature protection, as well as reverse current protection.
The AP2205 has 1.5V, 1.8V, 2.5V, 2.8V, 3.0V, 3.3V, 5.0V fixed voltage versions and an adjustable voltage version.
The AP2205 is available in the space-saving SOT25 and SOT89 packages.
