description

The 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 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 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

PowerPAD

 thermally-enhanced package for efficient heat management, and requires a copper plane to

dissipate the heat.
