Low quiescent current LDOs

ROHM has developed the BD7xxLx series of high-voltage (50V) LDO regulators for automotive applications featuring the industry's lowest dark current (6µA) – 80% lower than conventional LDO regulators – utilizing a proprietary circuit design, reducing power consumption significantly.

Together with the ultra-low IQ series ROHM is also offering BD4xxMx series, which is not so focused on the current consumption but is offering pin compatible offerings against competitor devices from Infineon, On-Semi and ST Microelectronics.

In later stage there is also the plan to introduce Linear Regulators with integrated Reset and optional WDT.

The main features of this series are:

• Ultra-low or low quiescent current
• Compact or standard packages (HTSOP, SOT223, TO252 or TO263)
• Output current capability: 200mA or 500mA
• High output voltage accuracy: ±2%
• Low saturation voltage by using PMOS output transistor
• Integrated overcurrent protection to protect the IC from damage caused by output short-circuiting
• Integrated thermal shutdown to protect the IC from overheating at overload conditions
• Low ESR ceramic capacitor can be used as output capacitor
