Overview:

The LD06AJSA/B is a current regulation integrated circuit with an input voltage range of 2.8V to 6V. It delivers a constant output current up to 1.5A, adjustable with an external resistor. Its design reduces external components, ideal for LED drivers and maintains stable operation when input voltage is above 2.8V.
This device features temperature regulation, ensuring continuous LED operation in high temperatures. When junction temperature reaches around 135°C, it reduces LED current to prevent further temperature rise, maximizing power handling and preventing damage.
The LD06AJSA/B incorporates a chip enable function to limit current consumption to 1uA when shut down.
It also includes an over-current protection mechanism that activates as LED current approaches 1.9A, preventing further increases.
