AP2138 ldo equivalent, ultra low quiescent current cmos ldo.
* Ultra-Low Quiescent Current: 1.0µA Typical
* Output Voltages: 1.2V, 1.4V, 1.5V, 1.8V, 2.1V, 2.2V, 2.5V, 2.8V,
3.0V, 3.3V, 3.6V and 4.0V
* High Output Voltag.
The AP2138/2139 series have 1.2V, 1.4V, 1.5V, 1.8V, 2.1V, 2.2V, 2.5V, 2.8V, 3.0V, 3.3V, 3.6V and 4.0V fixed output volt.
The AP2138/2139 series are CMOS-based positive voltage regulator ICs. Each of these ICs consists of a voltage reference, an error amplifier, a resistor network for setting output voltage and a current limit circuit for current protection.
