LND2931
100mA Low Dropout Voltage Regulator
DATA SHEET
GENERAL DESCRIPTION
3- terminal regulators ( To-220-5, SO-8
for LND2931)
100mA output within 2% over
temperature
Very low quiescent current
Low dropout voltage (300mV Typ)
Extremely tight load and line regulation
Very low temperature coefficient
Current and thermal limiting
Unregulated DC input can withstand
–20V reverse battery and +60V positive
transients
Direct replacement for National
LM2931 fixed series, but has lower
ground current, higher accuracy of
output voltage and extremely tight load
and line regulation. For adjust model
LND2931 see typical applications on
figure 2.
FEATURES
This series of fixed-voltage and adjustable
monolithic micropower voltage regulators is
designed for a wide range of applications. This
device is an excellent choice for use in battery-
powered application. Furthermore, the
quiescent current increases only slightly at
dropout, which prolongs battery life. This series
of fixed-voltage ( Typ. 60mV at light load and
300mV at 100mV) includes a tight initial
tolerance of 0.5% typ., extremely good load and
line regulation of 0.05% typ., and very low output
temperature coefficient. This series of fixed-
voltage and adjustable regulators is offered in 3-
pin TO-92 package (TO-220-5, SO-8 for
LND2931) compatible with other fixed-voltage
regulators.
APPLICATIONS
High-efficiency linear regulators
Battery powered systems
Portable/Palm top/ Notebook
Computers
Portable consumer equipment
Portable instrumentation
Automotive Electronics
