description
The TPPM0111 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 1.5-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.
