BD70HA5MEFJ-ME2

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

The BD70HA5MEFJ-ME2 is a single-output fixed linear low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed 7 V output with a maximum continuous current of 500 mA. The device operates within an input voltage range of 4.5 V to 8 V and features a typical dropout voltage of 600 mV at full load. It is housed in an HTSOP-J8 surface-mount package and supports an operating temperature range from -40°C to +105°C. The component holds AEC-Q100 qualification for automotive applications.

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

• Integrated shutdown function that reduces circuit current to zero during standby mode.
• Built-in thermal shutdown and overcurrent protection circuits to prevent damage under fault conditions.
• Soft-start capability to limit inrush current during power-up sequences.

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

• Automotive electronic systems requiring AEC-Q100 qualified components
• On-board infotainment and navigation unit power supplies
• Vehicle body electronics and control modules

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

Verify the NRND status before procurement, as this indicates the component is not recommended for new designs. Confirm availability through authorized distributors only. Ensure the specific suffix matches the required packaging and quality standards. Check for end-of-life notices or alternative part recommendations from the manufacturer prior to finalizing orders.

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

Select this regulator when a stable 7 V supply is needed for automotive loads up to 500 mA. The wide input range accommodates varying vehicle battery voltages. Consider the HTSOP-J8 package for space-constrained PCB layouts. Verify that the application does not require adjustable output or higher current capabilities beyond the specified 500 mA limit.

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

This component belongs to the BD70HA5 series of automotive LDO regulators designed for high reliability. It shares the same pinout and protective features as other variants in the family but differs in output voltage and current ratings. The series is engineered to meet strict automotive environmental and functional safety requirements.

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

Consult the official datasheet for direct pin-compatible substitutes within the BD70HA5 series. Verify if newer generation parts are available as alternatives due to the NRND status. Cross-reference electrical specifications carefully to ensure compatibility with existing system constraints.
