ADP5300ACPZ-2-R7

ADP5300 is a high efficiency, ultralow quiescent current step-down regulator without output discharge. The ADP5300 runs from a single input supply voltage, allowing the use of multiple alkaline or NiMH, Li-Ion cells, or other power sources. The total solution requires only four tiny external components. The ADP5300 can operate between hysteresis mode and pulse-width modulation (PWM ) mode via the SYNC/MODE pin. Typical application includes energy ( gas and water) metering, portable and battery-powered equipment and medical keep-alive power supplies.

• Input supply voltage range from 2.15V to 6.5V and operates down to 2V voltage
• Ultralow 180nA quiescent current and selectable output voltage of 0.8V to 5V
• ±1.5% output accuracy over full temperature range in PWM mode
• Selectable hysteresis mode or PWM operation mode
• Up to 50mA output current in hysteresis mode and up to 500mA output current in PWM mode
• VOUTOK flag monitors the output voltage and UVLO, OCP, and TSD protection
• Ultra fast stop switching control, 100% duty cycle operation mode, quick output discharge option
• 2MHz typ switching frequency in PWM mode with optional SYNC clock range from 1.5MHz to 2.5MHz
• 10 lead LFCSP package
• Operating temperature range from -40°C to 125°C
