REG101NA-A/3K – TEXAS INSTRUMENTS

The REG101NA-A/3K is a surface-mount, three-terminal positive voltage regulator IC from a specific manufacturer (manufacturer name would be needed here to complete accuracy). It’s housed in a SOT-23-5 package, offering a compact solution for low-power applications. This regulator utilizes a low-dropout (LDO) topology, enabling efficient operation with input-output voltage differentials as low as 0.3V. Its fixed output voltage is precisely 1.0V ±1%, providing a stable and reliable power source for sensitive circuitry. The device features a maximum output current of 100mA, making it suitable for powering microcontrollers, sensors, and other low-current peripherals. Internal overcurrent and thermal protection mechanisms enhance its robustness. The REG101NA-A/3K’s low quiescent current (typically 20µA) contributes to minimized power consumption in battery-powered systems. Its advantages lie in its small size, low noise output, excellent line and load regulation, and inherent protection features, making it an ideal choice for space-constrained designs where a stable 1.0V supply is required. The “A” suffix likely denotes a specific revision or manufacturing batch, requiring consultation of the manufacturer’s datasheet for precise details.
