Features & Applications

Microchip’s MCP1792 and MCP1793 are high-voltage, Low Dropout (LDO) regulators which supply a maximum output current of 100mA from a wide input-voltage range of 4.5V-55V. This capability makes the LDOs ideal for use in 12V, 24V or 48V power rails, and in high-voltage battery packs.

• Voltage supply to MCU or FPGA from battery power source
• Automotive electronics systems
• Power tools
• E-bikes
• Smoke detectors
• Alarm sensors

• Handles transient voltages up to 70V
• AEC-Q100 qualified to Grade 0
• PPAP capable
