GENERAL DESCRIPTION
1
L1087 Series
SOT-89,TO-92
AUG-30-2001
0.8A Fixed and Adjustable Low Dropout
Linear Regulator (LDO)
NIKO-SEM
The L1087 Series are positive and low
dropout three-terminal voltage regulators
with 0.8A output current capability. These
devices are designed for use in low voltage
applications that offers lower dropout volt-
age and faster transient response.
These devices are fully protected against
over current faults, over temperature oper-
ation, reversed input polarity, reversed lead
insertion, transient voltage spike …etc.
On-Chips trimming the reference voltage to
1% and features the low dropout of maxi-
mum 1.45 volts.
The L1087 Series regulators offer fixed and
adjustable voltage options available in the
space saving SOT-89 & TO-92 package.
