TB9045FNG-125
TR1, TR2, TR3
 It is a tracker power supply incorporating output driver MOS.  Output voltage is linked with LDO1.  Output current of TR1, TR2 or TR3 is maximum 100mA.  It incorporates functions of overcurrent detection (minimum 100mA for TR1, TR2 and TR3 respectively) and high/low voltage detection (TR1, TR2, and TR3). (Set current consumption considering allowable dissipation and heat generation.)  It enables turning off TR1, TR2 and TR3 independently via SPI communication.
