The LDLN025 is a 250 mA low-dropout voltage regulator, able to work with an input voltage range from 1.5 V to 5.5 V. The typical dropout voltage at 250 mA load is 120 mV.
The very low quiescent current, which is just 12 μA at no-load, extends battery-life of applications requiring very long standby time.
Thanks to its ultra low noise value and high PSRR, the LDLN025 provides a very clean output, suitable for ultra-sensitive loads. It is stable with ceramic capacitors.
The enable logic control function puts the device into shutdown mode allowing a total current consumption lower than 1 μA.
It includes short-circuit and thermal protection.
