The additional sleep MODE feature will reduce current consumption during standby operation to prolong the usage of battery. Dropout Voltage: 100mV maximum dropout with 150mA load. Shutdown: Less than 1µA quiescent current. Sleep Mode: Typically 14µA quiescent current during sleep MODE to reduce battery consumption. Enhanced Stability: The LP3987 is stable with minimum 1µF±20% low ESR ceramic output capacitor as low as 5mΩ and high quality tantalum capacitors. The LP3987 is available in a thin 5 Bump micro SMD package. Performance is specified for −40°C to 125°C. This device is available with output voltage options of 2.5V, 2.6V, 2.8V, 2.85V & 3.0V.
