BD00HA5WEFJ-E2

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

The BD00HA5WEFJ-E2 is a positive adjustable low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It operates within an input voltage range of 4.5 V to 8 V and delivers a maximum output current of 500 mA. The output voltage is adjustable from 1.5 V to 7 V, utilizing an internal reference voltage of 800 mV. Key electrical specifications include a typical dropout voltage of 600 mV and a maximum of 900 mV at full load. Line regulation is specified at 1%, while load regulation is 1.5%. The device functions reliably across an operating temperature range of -25°C to +85°C and is housed in an HTSOP-J8 surface-mount package.

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

Verify the complete part number including the suffix -E2 for environmental compliance status. Confirm the HTSOP-J8 package type matches your PCB footprint requirements. Check the specific datasheet revision for accurate thermal dissipation limits relative to your board layout. Ensure input and output capacitor selections meet the stability criteria defined in the official documentation.

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

Select this regulator for applications requiring a wide adjustable output range up to 7 V with moderate current capability. It is suitable where low quiescent current and small external component count are priorities. Consider the 8 V maximum input limit when designing against higher supply rails. The adjustable feature allows flexibility in setting precise voltage levels compared to fixed-output alternatives.

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

This component belongs to the BD00HA5WEFJ series of high-accuracy LDO regulators from ROHM. It shares the HTSOP-J8 package form factor with other variants in the family but differs in output current ratings and voltage ranges. The series is designed for general-purpose power management in consumer electronics, emphasizing size reduction through ceramic capacitor compatibility.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Consult the manufacturer's cross-reference guide for direct pin-compatible substitutes. Verify that any alternative maintains the same 500 mA output current and adjustable voltage range. Ensure thermal performance and package dimensions match the existing design constraints before substitution.
