ADP5300ACPZ-1-R7

Overview

The ADP5300ACPZ-1-R7 is a high-efficiency, ultralow power step-down regulator manufactured by Analog Devices Inc. It features a buck topology with a single programmable output ranging from 800 mV to 5 V. The device supports two selectable output current modes: 50 mA and 500 mA. It operates with an input voltage range of 2.15 V to 6.5 V and maintains a typical quiescent current of 260 nA. The switching frequency is fixed at 2 MHz. It is housed in a 10-lead LFCSP package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Ultralow power consumption with shutdown mode for extended battery life
• Dual-mode operation supporting both 50 mA and 500 mA load currents
• Integrated synchronous rectification for high efficiency across load ranges
• Fixed 2 MHz switching frequency enabling compact external component sizing

Applications

• Battery-powered portable electronics requiring efficient voltage regulation
• Wearable devices with strict space and power constraints
• IoT sensor nodes utilizing low standby current requirements
• Mobile communication equipment needing stable DC-DC conversion

Procurement Notes

Verify the specific suffix and package variant against the official Analog Devices datasheet to ensure compatibility with design specifications. Confirm RoHS compliance status and manufacturing origin details through authorized distribution channels. Cross-reference the part number with the latest product change notices to account for any material or packaging updates that may affect integration.

Selection Notes

Select this component when designing circuits that require a balance between low quiescent current and moderate output current capabilities. The dual-current mode allows optimization for both active and sleep states. Ensure the application input voltage remains within the 2.15 V to 6.5 V range. Consider the thermal performance of the LFCSP package if operating near maximum temperature limits or continuous full-load conditions.

Part Context

This part belongs to the ADP5300 series of ultralow power step-down regulators from Analog Devices. It shares functional similarities with the ADP5301 but differs in package type and specific pinout configuration. The series is designed for applications demanding high efficiency in small form factors, targeting mobile and wearable markets where power management is critical for system longevity.

Replacement Considerations

The ADP5301ACBZ-1-R7 is a documented alternative within the same family, offering similar electrical characteristics but in a different WLCSP package. Verify pin-to-pin compatibility and thermal dissipation requirements before substitution. Other members of the ADP530x series may serve as replacements if package differences are acceptable.
