APPLICATIU
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
30
μ
A 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 0.01
μ
F bypass capacitor,
output noise drops to 20
μ
V
RMS
over a 10Hz to 100kHz
bandwidth. The LT1763 regulators are stable with output
capacitors as low as 3.3
μ
F. Small ceramic capacitors can
be used without the series resistance required by other
regulators.
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.
