LT1763 Series

500mA, Low Noise, LDO

Micropower Regulators

FEATURES

DESCRIPTION

The LT

1763 series are micropower, low noise, low dropout

regulators. The devices are capable of supplying 500mA of

output current with a dropout voltage of 300mV. 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.

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

RMS

over 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.

Internal protection circuitry includes reverse battery

protection, current limiting, thermal limiting and reverse

current protection. The parts come in ﬁxed output voltages

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 8-lead SO and 12-lead, low

proﬁle (4mm

3mm

0.75mm) DFN packages.
