LT1763 Series

500mA, Low Noise, LDO

Micropower Regulators

FEATURES

DESCRIPTIO

The LT^®1763 series are micropower, low noise, low

dropout regulators. The devices are capable of supplying

500mAofoutputcurrentwithadropoutvoltageof300mV.

Designed for use in battery-powered systems, the low

30µA quiescent current makes them an ideal choice.

Quiescent current is well controlled; it does not rise in

dropout as it does with many other regulators.

■

Low Noise: 20µV_RMS(10Hz to 100kHz)

■

Output Current: 500mA

■

Low Quiescent Current: 30µA

■

Wide Input Voltage Range: 1.8V to 20V

■

Low Dropout Voltage: 300mV

■

Very Low Shutdown Current: < 1µA

■

No Protection Diodes Needed

Fixed Output Voltages: 1.5V, 1.8V, 2.5V, 3V, 3.3V, 5V

Adjustable Output from 1.22V to 20V

Stable with 3.3µF Output Capacitor

Stable with Aluminum, Tantalum or

Ceramic Capacitors

A key feature of the LT1763 regulators is low output noise.

With the addition of an external 0.01µF bypass capacitor,

output noise drops to 20µV_RMSover a 10Hz to 100kHz

bandwidth. The LT1763 regulators are stable with output

capacitors as low as 3.3µF. Small ceramic capacitors can

be used without the series resistance required by other

regulators.

■

Reverse Battery Protection

No Reverse Current

Overcurrent and Overtemperature Protected

8-Lead SO Package

Internal protection circuitry includes reverse battery pro-

tection, current limiting, thermal limiting and reverse

current protection. The parts come in fixed output volt-

ages of 1.5V, 1.8V, 2.5V, 3V, 3.3V and 5V, and as an

adjustable device with a 1.22V reference voltage. The

LT1763 regulators are available in the 8-lead SO package.
