Fixed LDO Voltage Regulator, 3.3V Out, 1A Out, TO-220-3

The TEXAS INSTRUMENTS Fixed LDO Voltage Regulator is designed to deliver a stable and reliable 3.3V output with a maximum current of 1A. This through-hole device, housed in a TO-220-3 package, features a fixed output voltage and a dropout voltage of 500mV, ensuring efficient operation in a wide range of applications. The regulator incorporates internal current limiting, safe area protection, and thermal shutdown, providing robust protection against virtually all overload conditions. These safety features help ensure long-term reliability and safeguard your electronic circuits from damage due to excessive current or heat. The low ground pin current allows the output voltage to be easily boosted above the preset value using a resistor divider, offering design flexibility. Additionally, the low quiescent current drain, with a specified maximum change with line and load, ensures good regulation even in voltage-boosted mode. The device is a green product, free from antimony and bromine, aligning with modern environmental standards. Its performance characteristics include high ripple rejection and a 4% tolerance on the preset output voltage, making it suitable for industrial and power management applications. With an operating temperature range of 0°C to 125°C, it can handle demanding environments. The component is supplied in a TO-220 package with 3 pins for straightforward PCB mounting. Hardware Note: Please note that this device has limited built-in ESD protection. During storage or handling, the leads should be shorted together or the device placed in conductive foam to prevent electrostatic damage to the MOS gates. This regulator is a reliable choice for engineers seeking a dependable power management solution.
