STMicroelectronics LDO Voltage Regulator 5V 3A TO-220-3
STMicroelectronics fixed & adjustable LDO voltage regulator, 5V out, 3A max, TO-220-3 package. Ideal for power management applications.
The STMicroelectronics Fixed and Adjustable LDO Voltage Regulator is a low drop positive voltage regulator capable of delivering up to 3A of output current. Designed to be pin-to-pin compatible with older 3-terminal adjustable regulators, this device provides improved performance regarding dropout voltage and output tolerance.
Unlike standard PNP regulators where a portion of the output current is wasted as quiescent current, this regulator directs the quiescent current into the load, thereby increasing overall efficiency. The dropout voltage is guaranteed at a maximum of 1.2V at the maximum output current, decreasing at lower loads. Stability is achieved with just a 10μF minimum capacitor.
Key Features
- Output tolerance of ±1% at 25°C and ±2% across the full temperature range
- Internal power and thermal limiting protection
- Pinout compatibility with standard adjustable voltage regulators
- Quiescent current flows into the load for enhanced efficiency
