LP2981IM5-3.6/NOPB TI LDO Voltage Regulator | SOT-23-5 | 100mA, 3.6V Output

Product Overview

The LP2981IM5-3.6/NOPB is a high-performance low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a fixed 3.6V output with a maximum output current of 100mA. Housed in a compact SOT-23-5 package, this device offers excellent line and load regulation, making it ideal for space-constrained applications requiring a stable and noise-free power supply. With a dropout voltage as low as 200mV at full load, the LP2981 ensures efficient operation even when the input voltage is close to the output voltage. The device also features a low quiescent current of 1.2mA (typical) and a shutdown mode that reduces current consumption to less than 1µA, extending battery life in portable devices.
