LP2980IM5-5.0 TI LDO Regulator | SOT-23-5 | 5.0V Output, 50mA

Product Overview

The LP2980IM5-5.0 from Texas Instruments is a high-performance, low-dropout (LDO) voltage regulator designed to deliver a fixed 5.0V output with a maximum output current of 50mA. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). With a dropout voltage as low as 120mV at full load, it ensures efficient operation even when the input voltage is close to the output. The LP2980IM5-5.0 features a low quiescent current of 1.2mA (typical) and a shutdown mode that reduces current to 0.01µA, making it suitable for battery-powered devices. Its stable operation with low-ESR ceramic output capacitors simplifies design and reduces external component count.
