R1501 Series
24V Input 1A Voltage Regulator

Product Specifications

The R1501 Series are CMOS-based voltage regulators featuring 1A output current and 24V input voltage. The R1501 series provides high input voltage operation and low on-resistance (at VSET=10V, below 0.6Ω) because of using DMOS transistor. In addition to a fold-back protection circuit built into conventional regulators, R1501 contains a thermal shutdown circuit. Besides the low supply current by CMOS, the operating temperature is -40°C to 105°C and the maximum input voltage is 24V, the R1501 series are very suitable for power source of car accessories.

R1501 Series for Automotive

Ricoh is committed to providing a semiconductor device with the highest level of quality and reliability by restricting the device manufacturing only within Ricoh and the cooperative companies successfully passed our stringent inspections for automotive products. Ricoh established a traceability system and manages manufacturing information and logistics information from the warehouse.


Quality Ranks for Applications

Ricoh offers three different quality ranks for automotive products according to their application purposes.
The R1501J is suitable for use in the Rank 2 and Rank 3 applications, and the R1501S is for use in the Rank 3 application.

Rank 2: Automotive General Equipments (Body System)

  • Power source for automotive general equipments such as electric window, side mirror, and around view camera

Rank 3: Automotive Accessories

  • Power source for car accessories such as car audio equipment, car navigation system, and ETC system

AEC-Q100 Grade 2 Compliant
