MCP1781T-5002H/DC - High-Voltage Low Dropout Linear Regulator
The MCP1781T-5002H/DC from Microchip Technology is a precision 200mA high-voltage low dropout (LDO) linear voltage regulator designed for demanding industrial and automotive applications. This fixed 5V output regulator accepts input voltages up to 55V, making it ideal for systems requiring stable voltage regulation from high-voltage power sources.
Key Features & Benefits
- Wide Input Voltage Range: Operates from input voltages up to 55V, perfect for automotive and industrial power systems
- Low Dropout Voltage: Only 0.705V dropout at 200mA output current ensures efficient power conversion
- Ultra-Low Quiescent Current: 57µA typical quiescent current minimizes power consumption in standby mode
- Excellent PSRR Performance: 80dB to 36dB power supply rejection ratio at 100kHz reduces noise from input supply
- Comprehensive Protection: Built-in overcurrent, over-temperature, short circuit, and UVLO protection safeguards your circuit
- Compact Surface Mount Package: SOT-223-6 package saves valuable PCB space
- High Reliability: Extended operating temperature range from -40°C to 150°C (TJ) ensures reliable operation in harsh environments
- Enable Control: Integrated enable pin allows for easy power sequencing and shutdown control
Performance Characteristics
The MCP1781T-5002H/DC delivers exceptional performance across a wide range of operating conditions. With its ultra-low quiescent current of just 57µA, this LDO regulator is ideal for battery-powered applications where power efficiency is critical. The device maintains excellent line and load regulation, ensuring stable 5V output even with fluctuating input voltages up to 55V.
The regulator's impressive power supply rejection ratio (PSRR) of 80dB at low frequencies effectively filters out input voltage noise, making it perfect for noise-sensitive analog circuits, precision sensors, and microcontroller power supplies. The low dropout voltage of only 0.705V at full 200mA load maximizes efficiency and allows operation with minimal headroom between input and output voltages.
Applications
The MCP1781T-5002H/DC is perfectly suited for:
- Automotive Electronics: Infotainment systems, dashboard displays, sensor modules, and ECU power supplies
- Industrial Control: PLC systems, motor controllers, automation equipment, and process control instrumentation
- Battery-Powered Devices: Portable test equipment, handheld instruments, and wireless sensor nodes
- Point-of-Load Regulation: Distributed power systems requiring local voltage regulation
- Microcontroller Power: Stable power supplies for MCUs, DSPs, and embedded processors
- Communication Equipment: Networking devices, IoT modules, and telecommunication systems
- Medical Devices: Portable diagnostic equipment and patient monitoring systems
Design Considerations
When implementing the MCP1781T-5002H/DC in your design, consider adding input and output capacitors for optimal stability and transient response. A minimum 1µF ceramic capacitor on the input and 2.2µF on the output is recommended. The enable pin can be used for power sequencing or connected to the input voltage for always-on operation. Ensure adequate thermal management for applications operating at high ambient temperatures or maximum output current.
