The **BD772-R_13** is a high-performance power management component, specifically a **Low Dropout (LDO) Linear Regulator** manufactured by ROHM Semiconductor. It is designed for applications requiring high reliability, low noise, and stable voltage regulation. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Component Type** | LDO Linear Voltage Regulator | | **Output Type** | Fixed / Adjustable (depending on variant) | | **Output Current** | Typically up to 1.0A or 2.0A (series dependent) | | **Input Voltage Range** | 4.5V to 36V | | **Package Type** | TO-252 (DPAK) or HRP5 | | **Temperature Range** | -40°C to +150°C | --- ### 2. Core Electronic Features #### High Voltage Resistance The BD772 series is designed to handle wide input voltage swings, making it suitable for automotive and industrial environments where voltage spikes are common. #### Protection Circuitry The part includes several internal safeguards to ensure longevity: * **Over Current Protection (OCP):** Prevents the device from burning out if the load draws too much current. * **Thermal Shutdown (TSD):** Automatically shuts the chip off if the internal temperature exceeds safety limits. * **Reverse Current Protection:** Prevents damage if the output voltage becomes higher than the input voltage. #### Low Quiescent Current It is optimized for low power consumption during standby modes, which is critical for battery-operated systems or "Always-on" automotive modules. --- ### 3. Common Applications * **Automotive Units:** Powering Electronic Control Units (ECUs), infotainment systems, and dashboard displays. * **Industrial Equipment:** Power supplies for factory automation and PLC controllers. * **Consumer Electronics:** High-efficiency power regulation for home appliances and audio equipment. --- ### 4. Typical Application Circuit When integrating the BD772-R_13, capacitors are required for stability: ```cpp // Schematic Logic Representation [Input Voltage (Vin)] --- [C_in (0.1uF to 10uF)] --- [BD772 Vin Pin] | [BD772 Vout Pin] --- [C_out (1uF to 47uF)] --- [Load] | [BD772 GND Pin] --- [Ground] ``` ---
