Overview
The ADP5304ACPZ-2-R7 is a single-output ultra-low power (ULP) buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 2.15 V to 6.5 V and provides a programmable output voltage from 800 mV to 5 V. The device supports a maximum output current of 50 mA, with a peak capability of 500 mA. Key electrical specifications include a quiescent current of 260 nA and a fixed switching frequency of 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
- Ultra-low quiescent current consumption for extended battery life
- Integrated synchronous rectification for high efficiency
- Programmable output voltage via external resistor divider
- Built-in shutdown mode to minimize standby power
Applications
- Battery-powered portable electronic devices
- Wearable health monitoring equipment
- IoT sensor nodes requiring efficient power management
- Mobile communication modules
Procurement Notes
Verify the specific suffix '-R7' indicates reel packaging when sourcing. Confirm the 'ACPZ' designation corresponds to the commercial temperature grade and LFCSP-10 package variant. Ensure compatibility with the ADP5304-EVALZ development kit for initial circuit validation. Check for moisture sensitivity labeling prior to surface mount assembly.
Selection Notes
Select this component for applications requiring a compact step-down solution with minimal static current draw. The 2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Ensure the load current does not exceed the 50 mA continuous rating for optimal thermal performance. Consider the 6.5 V maximum input limit when designing for higher voltage source environments.
Part Context
This part belongs to the ADP5304 series of ULP buck regulators designed for space-constrained mobile applications. It complements other Analog Devices PMICs by offering a dedicated low-current step-down channel. The device integrates features typical of modern portable electronics power chains, focusing on efficiency and size reduction.
Replacement Considerations
The ADP5301ACBZ-1-R7 is a documented substitute within the same family, featuring similar electrical characteristics but utilizing a 9-WLCSP package instead of the LFCSP-10 form factor.
