1.5A Low Dropout
Linear Regulator
LD1086 Series
1.5A Low Dropout Linear Regulator
General Description
The LD1086 is a series of low dropout positive voltage regulators with
a maximum dropout of 1.5V at 1.5A of load current.
The LD1086 series is available in 1.5V, 1.8V, 2.5V, 3.0V, 3.3V and 5.0V
versions. The fixed versions integrate the adjust resistors. It is also
available in an adjustable version which can set the output voltage with
two external resistors.
The LD1086 series features on-chip thermal shutdown. It also includes
a band gap reference and a current limiting circuit.
The LD1086 series is available in standard packages of DPAK(TO-252-2),
D2PAK(TO-263-3), TO-220 and SOT-223.
Features
Low dropout voltage: 1.3V typical at 1.5A
Current limiting and thermal protection
Output current: 1.5A
Current limit: 2.3A
Operation junction temperature: 0 to 125°C

Note: 1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent
damage to the device. These are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated “Recommended Operating Conditions”
is not implied. Exposure to “Absolute Maximum Ratings” for extended period may affect device
reliability.
2. Absolute maximum ratings indicate limits, beyond which damage to the component may occur.
Electrical specifications do not apply when operating the device outside of its operating ratings.
