Unlike the other GP2AP* schemas, this is strictly a proximity sensor and NOT an ambient light sensor. For power supplies, it expects two voltage supplies, one for core and other for driving the infrared LED which is used to measure proximity distance. However, some variants may not explicitly require a separate regulator for the LED as they're able to draw power from the main supply. This chip has been used in production mobile devices such as the Samsung Galaxy J6.
