| Description The SE9135 is a low dropout current regulator rated for 350mA constant sink current. The constant sink current will ensure that the same amount of power is applied to the power LED and consequently maintain the uniform brightness throughout the possible voltage variations from the power source. The IC also features low quiescent current and is typically at 212uA. This will minimize the power consumption from the IC itself. The IC has EN function built-in for applications where EN function or Dim function is needed. Please contact us directly if EN function is required. SE9135 is presently available in low profile SOT-89-3L and TO-252 packages. Features No external component required. Constant 350mA constant sink current. Output short / open circuit protection. Low dropout voltage. Low quiescent current at 212uA typical. Build-in thermal protection. Supply voltage range 2.7V ~ 6V. 2KV HBM ESD protection. Advanced CMOS process. SOT-89 and TO-252 package. EN function is available upon request. Application Power LED Driver. LED Flashlight Torch. LED Miner's Lamp. Lighting.

Note 2: Output dropout voltage: 90% x IOUT @ VOUT=200mV Thermal Considerations It is important that the thermal limit of the package is not exceeded. The power dissipation for a given application can be calculated as following: The power dissipation (PD) is PD = IOUT * [VIN - VOUT] The thermal limit of the package is then limited to PD(MAX) = [TJ - TA]/JA where TJ is the junction temperature, TA is the ambient temperature, and JA is around 180C/W for SE9135. SE9135 is designed to enter thermal protection at 150C. For example, if TA is 25C then the maximum PD is limited to about 0.7W. In other words, if IOUT(MAX) = 350mA, then [VIN - VOUT] cannot exceed 2V. The SE9135 has built-in thermal protection. When the thermal limit is exceeded, the IC will enter protection, and VOUT will be pulled to ground.
