Complete Power Management Solution for  
USB High-Power Peripherals  
The TPS2140/41/50/51 is a USB 1.0 and 2.0  
Specification-compatible IC containing a dual-current-  
limiting power switch and an adjustable low dropout  
regulator (LDO). Both the switch and LDO limit inrush  
current by controlling the turnon slew rate. The unique  
dual-current-limiting feature of the switch allows USB  
peripherals to utilize high-value capacitance at the  
output of the switch, while keeping the inrush current  
low. During turnon, the switch limits the current  
delivered to the capacitive load to less than 100 mA.  
When the output voltage from the switch reaches about  
93% of the input voltage, the switch power good output  
goes high, and the switch current limit increases to  
800mA (minimum), at which point higher current loads  
can be turned on. The higher current limit provides short  
circuit protection while allowing the peripheral to draw  
maximum current from the USB bus.  
250 mA Low-Dropout Regulator (LDO) With  
Enable and 325 mA (Typ) Current Limit  
LDO Supports 2.7 V to 5.5 V V and 0.9 V to  
IN  
3.3 V Adjustable V  
OUT  
40 mΩ (Typ) High-Side MOSFET With Dual  
Current Limit  
Undervoltage Lockout and Power Good for  
LDO and Switch  
CMOS- and TTL-Compatible Enable Inputs  
85 µA (Typ) Supply Current  
5 µA (Typ) Standby Supply Current  
Available in 14-Pin HTSSOP (PowerPAD )  
–40°C to 85°C Ambient Temperature Range  
Alternative to TPS2148/58 3.3-V LDO With  
3.3-V Switch and 5-V Switch  
The switch and LDO function independently, providing  
flexibility in DSP applications requiring separate core  
and I/O voltages. For example, in a DSP application  
operating from a 3.3-V rail, the LDO can supply the DSP  
core voltage down to 0.9 V, while the switch powers the  
3.3-V (typical) DSP I/O supply. If supply sequencing is  
required, the LDO power good output can be used to  
enable the switch.
