Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for BD3522EFV-E2

BD3522EFV-E2

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BD3522EFV-E2 is an ultra-low dropout linear regulator manufactured by ROHM Semiconductor, designed for high-current applications such as desktop PCs. It features a single adjustable output voltage ranging from 650 mV to 2.7 V and supports a maximum output current of 4 A. The device operates within an input voltage range of 1.25 V to 5.5 V and dissipates up to 3.2 W of power. It is housed in a 20-pin HTSSOP package with an exposed pad, suitable for surface mount installation. The component functions reliably across an operating temperature range of -10°C to +100°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Ultra-low dropout architecture enables efficient regulation with minimal voltage difference between input and output.
High current capability delivers up to 4 A output for demanding load requirements.
Adjustable output voltage allows flexible configuration within the specified low-voltage range.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS compliance status. Confirm that the 20-pin HTSSOP package dimensions match the target PCB footprint. Ensure thermal management strategies account for the 3.2 W power dissipation rating under maximum load conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed low-voltage LDO is insufficient due to varying system rail requirements. The adjustable output feature provides design flexibility for different core voltages. Consider the 4 A current capacity and thermal performance in the HTSSOP package when designing the heat dissipation path for continuous operation.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context
