Low IQ: 1µA  
microprocessor-compatible input. This LDO is  
designed specifically for battery-powered applications  
where dual-level voltages are needed. With ultralow  
IQ (1µA), microprocessors, memory cards, and smoke  
detectors are ideal applications for this device.

Low Dropout: 200mV at 150mA  
3% Accuracy Over Load/Line/Temperature  
The ultralow-power and selectable dual-level output  
voltages allow designers to customize power  
consumption for specific applications. Designers can  
now shift to a lower voltage level in a battery-powered  
design when the microprocessor is in sleep mode,  
further reducing overall system power consumption.  
The two voltage levels are preset at the factory  
through a unique architecture using an EPROM. The  
EPROM technique allows for numerous output  
voltage options between VSET low (1.5V to 4.2V) and  
VSET high (2.0V to 3.0V) in the fixed output version  
only. Consult with your local factory representative for  
exact voltage options and ordering information;  
minimum order quantities may apply.

Available in DDC (TSOT23-5) or DRV (2mm ×

The TPS781 series are designed to be compatible  
with the TI MSP430 and other similar products. The  
enable pin is compatible with standard CMOS logic.  
This LDO is stable with any output capacitor greater  
than 1.0µF. Therefore, implementations of this device  
require minimal board space because of miniaturized  
packaging and a potentially small output capacitor.  
The TPS781 series IQ (1µA) also come with thermal  
shutdown and current limit to protect the device  
during fault conditions. All packages have an  
operating temperature range of TJ = –40°C to  
+125°C. For high-performance applications requiring  
a dual-level voltage option, consider the TPS780  
series, with an IQ of 500nA and dynamic voltage  
scaling.

DESCRIPTION  
The TPS781 family of low-dropout (LDO) regulators  
offer the benefits of ultralow power (IQ = 1µA),  
miniaturized packaging (2×2 SON-6), and selectable  
dual-level output voltage levels. An adjustable version  
is also available, but does not have the capability to  
shift voltage levels.
