SLVS373 AUGUST 2001
3.3-V LDO AND DUAL SWITCH FOR USB PERIPHERAL POWER MANAGEMENT
FEATURES DESCRIPTION
The TPS2148 incorporates two power distribution switches and an LDO in one small package, providing a USB peripheral power management solution that saves up to 60% in board space over typical implementations. The TPS2148 meets USB 2.0 bus-powered peripheral requirements. An integrated LDO regulates the 5-V bus power down to 3.3 V for the USB controller, and a MOSFET switch that is internally connected to the output of the LDO simplifies meeting the suspend and enumeration current requirements imposed by the USB specification. A second switch is available to support a downstream port, stage power to a second voltage regulator, or disable power to selected circuitry in power-save modes. Each power-distribution switch is capable of supplying 200 mA of continuous current, and the independent logic enables are compatible with 5-V logic and 3-V logic. The switches and the LDO are designed with controlled rise times and fall times to minimize current surges. The TPS2148 has active-low enables while the TPS2158 has active-high enables.

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. All voltages are with respect to GND.
