LC1500
REV1.2-Revised May 2010
500mA, Wide Input Voltage, Low Consumption Linear Regulator
DESCRIPTION
FEATURES
LC1500 series is a group of positive voltage
output, low power consumption, low dropout
voltage regulator.
LC1500 can provide output value in the range
of 1.2V~6.0V every 0.1V step. It also can be
customized on command.
LC1500 includes high accuracy voltage
reference, error amplifier, current limit circuit
and output driver module with discharge
capability.
LC1500 has excellent load and line transient
response and good temperature
characteristics, which can assure the stability
of chip and power system. And it uses
trimming technique to guarantee output
voltage accuracy within ±2%.
LC1500 is available in SOT23-5 or DFN2*2-8
packages which is lead free. It also can
available in these packages with lead.
