BD00HC5WEFJ-E2

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

The BD00HC5WEFJ-E2 is a high-accuracy adjustable low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a maximum output current of 1.5 A with an input voltage range from 4.5 V to 8 V. The device supports an adjustable output voltage between 1.5 V and 7 V, achieving ±1.0% accuracy at 25°C. Key electrical parameters include a typical dropout voltage of 600 mV at full load, a quiescent current of 600 µA, and a ripple rejection of 60 dB. It operates within a temperature range of -25°C to +85°C and features thermal shutdown and overcurrent protection circuits.

• Built-in overcurrent protection and thermal shutdown circuits to prevent IC damage
• Capable of supporting ceramic output capacitors for compact design

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

• Digital home appliances
• Portable electronic devices requiring efficient power management
• General-purpose linear regulation in consumer electronics

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

Verify the specific suffix E2 against the official ROHM datasheet to confirm compliance with RoHS standards and lead-free specifications. Ensure the HTSOP-J8 package variant matches the required PCB footprint. Confirm that the application does not involve automotive environments, as this standard-grade product is explicitly not recommended for such use cases.

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

Select this component when a 1.5 A output current is required with an adjustable voltage setting up to 7 V. It is suitable for designs needing high accuracy (±1%) and low quiescent current. Consider the 600 mV dropout voltage relative to the minimum input voltage of 4.5 V to ensure sufficient headroom. Verify compatibility with ceramic capacitors to minimize board space.

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

This part belongs to the BD00HC5WEFJ series of LDO regulators from ROHM Semiconductor. The series includes both fixed-output variants (such as BD33HC5WEFJ-E2) and adjustable versions. The BD00HC5WEFJ-E2 specifically offers flexibility through its adjustable output range while maintaining the series' high accuracy and protection features in an 8-pin surface-mount package.

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

Direct substitutes within the same family include other adjustable or fixed-output variants like the BD00HA5WEFJ-E2 (0.5 A) or BD00HA3WEFJ-E2 (0.3 A), though these have lower current ratings. Fixed-output equivalents such as BD33HC5WEFJ-E2 provide similar performance but lack adjustability.
