TPS783  
SBVS133A –FEBRUARY 2010–REVISED NOVEMBER 2014  
TPS783xx 500-nA IQ, 150-mA, Ultralow Quiescent Current  
Low-Dropout Linear Regulator  
1 Features  
3 Description  
The TPS783 family of low-dropout regulators (LDOs)  
offers the benefits of ultralow power and miniaturized  
packaging.

Input Voltage Range: 2.2 V to 5.5 V  
Low Quiescent Current (IQ): 500 nA  
150-mA, Low-Dropout Regulator  
This LDO family is designed specifically for battery-  
powered applications where ultralow quiescent  
current is a critical parameter. The TPS783, with  
ultralow IQ (500 nA), is ideal for microprocessors,  
microcontrollers,  
applications.  
Low-Dropout at 25°C, 130 mV at 150 mA  
Low-Dropout at 85°C, 175 mV at 150 mA  
3% Accuracy Over Load, Line, and Temperature  
Stable with a 1.0-μF Ceramic Capacitor  
Thermal Shutdown and Overcurrent Protection  
CMOS Logic Level-Compatible Enable Pin  
DDC (SOT-5) Package  
and  
other  
battery-powered  
The absence of pulldown circuitry at the output of the  
LDO provides the flexibility to use the regulator output  
capacitor as a temporary backup power supply (for  
example, during battery replacement).  
2 Applications  
The ultralow power and miniaturized packaging allow  
designers to customize power consumption for  
specific applications. Consult with your local factory  
representative for exact voltage options and ordering  
information; minimum order quantities may apply.

TI MSP430 Attach Applications  
Wireless Handsets and Smartphones  
MP3 Players  
Battery-Operated Handheld Products  
The TPS783 family is compatible with the TI MSP430  
and other similar products. The enable pin (EN) is  
compatible with standard CMOS logic. This device  
allows for minimal board space because of  
miniaturized packaging and a potentially small output  
capacitor. The TPS783 family also features thermal  
shutdown and current limit to protect the device  
during fault conditions. All packages have a specified  
operating temperature range of TJ = –40°C to 105°C.
