Stresses beyond 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 under !recommended operating conditions! is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:1.All voltage values are with respect to GND.
2.Absolute negative voltage values on these terminals should not be below -0.5 V.
3.Assumed correct thermal management technique implementation and ambient temperature of 25.
DescriptionThe TPPM0110 is a power source intended for use in systems that have a single 5-V input source and require dual, linearly-regulated, low-dropout voltage sources. The outputs of TPPM0110 must track within 2 V of each other during all conditions and modes of operation. Each output is protected against overcurrent conditions. In the event that one of the outputs is shorted to ground, the other output must maintain a voltage output differential of less than 2 V compared to the output with the abnormal condition.
The 3.3-V ±3% regulated output of TPPM0110 is capable of driving loads of 1.5 A, and the 1.8-V ±2% regulated output is capable of driving loads of 300 mA under all normal operating conditions. The device is available in a PowerPADTM thermally-enhanced package for efficient heat management, and requires a copper plane to dissipate the heat.
