The LP8345IDTX-2.5 is a fixed 2.5V low dropout linear regulator capable of delivering 500mA. Its ultra-low 50µA quiescent current and 0.65V dropout voltage make it suitable for battery-powered and industrial applications. The TO-252-3 package ensures efficient heat dissipation, while 55dB PSRR at 120Hz provides clean output for sensitive loads.
- Ultra-low quiescent current (50µA) – extends battery life in portable devices.
- High output current (500mA) – supports a wide range of loads.
- Low dropout (0.65V @ 500mA) – allows efficient operation from lower input rails.
- Good PSRR (55dB @ 120Hz) – reduces ripple from switching supplies.
