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
