The LP2954IS/NOPB is a 5V micropower low-dropout voltage regulator from Texas Instruments, designed to provide a stable output voltage with a maximum output current of 250 mA. It features a low quiescent current of 90 ¬µA at a 1 mA load, which increases only slightly to 120 ¬µA during dropout conditions, making it suitable for battery-powered applications. The dropout voltage is typically 60 mV at light loads and 470 mV at full load, ensuring efficient operation. The device includes reverse battery protection and offers tight line and load regulation, with a typical output accuracy of 1.2% over temperature. It is available in a DDPAK/TO-263 package and operates over a temperature range of -40¬8C to 125¬8C. This regulator is pin-compatible with the LM2940 and LM340, facilitating easy integration into existing designs.
