.The APL5611CI-TRG is a Low Dropout Regulators (LDO) SOT-23-6 RoHS manufactured by Anpec. It features an output voltage range of 2.5 V to 5.5 V, maximum output current of 250 mA, minimum input voltage of 1.8 V, quiescent current of 2 µA, and Line Regulation of 0.02%. It has very low dropout voltage and tight output voltage accuracy, making it suitable for powering low voltage, high accuracy applications such as portable/battery powered devices, handheld devices, Bluetooth-enabled devices, and mobile phones. The device also has a high efficiency due to its low quiescent currents and ultra-low dropout characteristics. This ensures that it can operate optimally in battery environments, conserving energy while the system is in standby mode. The device is available in a small 6-Pin SOT-23 Package, making it ideal for space-constrained applications.
