The AP2139AK-1.8TRG1 from Diodes Incorporated is a CMOS-based positive voltage regulator IC designed for portable applications. It offers a fixed output voltage of 1.8V with a maximum output current of 250mA.
Key electrical characteristics include an ultra-low typical quiescent current of 1.0µA and a low dropout voltage of 25mV at 10mA. The device also provides high output voltage accuracy of ±2% and features over-current protection. Its operating temperature range is -40°C to 85°C.
The AP2139AK-1.8TRG1 is supplied in a SOT-23-5 surface-mount package. It includes logic-controlled enable and an active quick output discharge function, differentiating it from the AP2138 series. This regulator is ideal for battery-powered equipment and other portable devices requiring efficient power management.
