LTC1258 Series

Micropower Low

Dropout References

FEATURES

DESCRIPTIO

200mV Max Dropout at 10mA Output Current

The LTC^®1258/LTC1258-2.5/LTC1258-3/LTC1258-4.1/

LTC1258-5 are micropower bandgap references that

combine high accuracy and low drift with very low supply

currentandsmallpackagesize.Thecombinationofultralow

quiescent current and low dropout voltage of only 200mV

max. makes them ideal for battery-powered equipment.

The output voltage is set by an external resistor divider for

the adjustable LTC1258.

■

4µA Typical Quiescent Current

■

0.15% Max Initial Accuracy (S8)

No Output Capacitor Required

Output Sources 10mA, Sinks 2mA

40ppm/°C Max Drift (S8)

Available in Small MSOP Package

Voltage Options: 2.5V, 3V, 4.1V, 5V and Adjustable

This series of references uses curvature compensation to

obtain low temperature coefficient and trimmed thin-film

resistors to achieve high output accuracy. These refer-

ences can source up to 10mA and sink up to 2mA, making

them ideal for precision regulator applications. They are

stable without an output bypass capacitor, but are also

stablewithcapacitanceupto1µF.Thisfeatureisimportant

incriticalapplicationswherePCboardspaceisapremium

and fast settling is demanded.

APPLICATIO S

■

Battery-Powered Systems

■

Handheld Instruments

■

Precision Power Supplies

■

A/D and D/A Converters

The LTC1258 series references provide power dissipation

advantages over shunt references. In addition to supply

current, shunt references must also idle the entire load

current to operate.

The LTC1258 series is available in the 8-pin MSOP and SO

packages.
