TEXAS INSTRUMENTS Fixed LDO Voltage Regulator, 3.3V 100mA, SOT-23-3

The TEXAS INSTRUMENTS Fixed LDO Voltage Regulator is a high-performance, low-dropout linear voltage regulator designed for stable and efficient power management. It provides a fixed 3.3V output from a wide input voltage range of 4.2V to 30V, making it highly versatile for a variety of electronic applications. With a maximum output current of 100mA, it is ideal for powering low-power microcontrollers, sensors, and other integrated circuits that require a clean and reliable voltage supply.

A key advantage of this regulator is its exceptionally low dropout voltage of just 300mV, which allows it to continue regulating the output voltage even when the input voltage is very close to the desired output level. This feature maximises efficiency and extends battery life in portable devices. The device is housed in a compact SOT-23-3 surface-mount package, saving valuable board space in modern, miniaturised electronic designs.
