Description
General part information
LDLN025 Series
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.
