LN6206
Low Power Low Dropout Middle Current Voltage Regulators
■ General Description
The LN6206 series are precise, low power consumption,
high voltage; positive voltage regulators manufactured
using CMOS and laser trimming technologies. The series
provides large currents with a significantly small dropout
voltage. The LN6206 consists of a current limiter circuit, a
driver transistor, a precision reference voltage and an error
correction circuit. The series is compatible with low ESR
ceramic capacitors. The current limiter's feedback circuit
also operates as a short protect for the output current
limiter and the output pin. Output voltage can be set
internally by laser trimming technologies. It is selectable in
100mV increments within a range of 1.2V to 5.0V.
SOT-89-3, SOT-23-3 and SOT23-3B packages are
available.

■ Application Conditions
LN6206
Input capacitor (CIN): 1.0µF or more
Output capacitor (CL):0.1 µF or more (tantalum capacitor)
Caution A general series regulator may oscillate, depending on the external components selected. Check that no
oscillation occurs with the application using the above capacitor.
