Typical applicaTion
DescripTion
300mA, Low Noise,
Micropower
LDO Regulators
The LT
®
1962 series are micropower, low noise, low dropout
regulators. The devices are capable of supplying 300mA
of output current with a dropout voltage of 270mV. De
-
signed 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 LT1962 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 LT1962 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 protec
-
tion, 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 LT1962 regulators are
available in the 8-lead MSOP package.
