TPS2148  
TPS2158  
SLVS373 – AUGUST 2001  
3.3-V LDO AND DUAL SWITCH  
FOR USB PERIPHERAL POWER MANAGEMENT  
FEATURES  
DESCRIPTION  
Complete Power Management Solution for  
USB Bus-Powered Peripherals  
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.  
3.3-V 200 mA Low-Dropout Voltage Regulator  
With Enable  
3.3-V 340-mΩ (Typ) High-Side MOSFET  
5-V 340-mΩ (Typ) High-Side MOSFET  
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.  
Independent Thermal- and Short-Circuit  
Protection for LDO and Each Switch  
2.9-V to 5.5-V Operating Range  
CMOS- and TTL-Compatible Enable Inputs  
75-µA (Typ) Supply Current  
Available in 8-Pin MSOP (PowerPAD )  
–40°C to 85°C Ambient Temperature Range  
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.  
APPLICATIONS  
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.  
USB Peripherals  
– Digital Cameras  
– Zip Drives  
– Speakers and Headsets  
The TPS2148 has active-low enables while the  
TPS2158 has active-high enables.
