The LT ? 1762 series are micropower, low noise, low
dropout regulators. The devices are capable of supplying
150mA of output current with a dropout voltage of 270mV.
Designed for use in battery-powered systems, the low
25 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 LT1762 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 LT1762 regulators are stable with output
capacitors as low as 2.2 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 2.5V, 3V, 3.3V and 5V, and as an adjustable device
with a 1.22V reference voltage. The LT1762 regulators are
available in the 8-lead MSOP package.
