DESCRIPTION
The LP3987 is a 150mA fixed output voltage
regulator with very low dropout voltage designed
specially to meet requirements of battery-powered
applications. 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 DSBGA
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, and 3.0V. For other voltage
options, please contact Texas Instruments.
