LP3987
Micropower micro SMD 150 mA Ultra Low-Dropout
CMOS Voltage Regulators with sleep MODE
General Description
The LP3987 is a 150mA fixed output voltage regulator with
very low dropout voltage designed specially to meet require-
ments 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 5m
and high quality tantalum capacitors.
The LP3987 is available in thin and thick 5 Bump micro SMD
package. Performance is specified for 40C to 125C.
This device is available with output voltage options of 2.6V,
2.8V, & 2.85V. For other voltage options, please contact
National Semiconductor Corporation.
