Overview
The ADP5300ACPZ-1-R7, produced by Analog Devices Inc., is a high-efficiency, ultralow quiescent current step-down regulator. This regulator is designed to operate from an input supply voltage range of 2.15 V to 6.50 V, making it suitable for use with multiple alkaline or NiMH, Li-Ion cells, or other power sources. It offers a selectable output voltage from 0.8 V to 5.0 V, adjustable via an external VID resistor and factory fuse. The device is highly efficient and can operate in both hysteresis mode and pulse-width modulation (PWM) mode, providing up to 50 mA in hysteresis mode and up to 500 mA in PWM mode.
