microprocessor-compatible input. This LDO is

designed specifically for battery-powered applications

where dual-level voltages are needed. With ultralow

I_Q(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 V_SETlow (1.5V to 4.2V) and

V_SEThigh (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 ×

2mm SON-6) Package Options

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 I_Q(1µA) also come with thermal

shutdown and current limit to protect the device

during fault conditions. All packages have an

operating temperature range of T_J= –40°C to

+125°C. For high-performance applications requiring

a dual-level voltage option, consider the TPS780

series, with an I_Qof 500nA and dynamic voltage

scaling.

DESCRIPTION

The TPS781 family of low-dropout (LDO) regulators

offer the benefits of ultralow power (I_Q= 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.
