Note :
1. Thermal Resistance is specified with the component mounted on a low effective thermal conductivity test
board in free air at T_A=25°C.
2. Output Dropout Voltage: Duty 90% x I_OUT@V_OUT=0.5V.

EN
Output Stage Enable Control pin. High enable the output pin. It can be left
floating for normally on.

OUT
Output pin. Sink current is decided by the current on R_SET connected to I_SET
pin. I_OUT=500 x I_SET=500 x 1.2V/R_SET
