The LT ? 3029 is a dual, micropower, low noise, low drop-
out linear regulator. The device operates either with a
common input supply or independent input supplies for
each channel, over an input voltage range of 1.8V to 20V.
Each output supplies up to 500mA of output current with
a typical dropout voltage of 300mV. Quiescent current is
well controlled in dropout. With an external 10nF bypass
capacitor, output noise is only 20μV RMS over a 10Hz to
100kHz bandwidth. Designed for use in battery-powered
systems, the low 55μA quiescent current per channel makes
it an ideal choice. In shutdown, quiescent current drops to
less than 1μA. Shutdown control is independent for each
channel, allowing for ?exible power management.
The LT3029 optimizes stability and transient response with
low ESR ceramic output capacitors, requiring a minimum
of only 3.3μF. The regulator does not require the addition
of ESR, as is common with other regulators.
Internal circuitry provides reverse-battery protection,
reverse-current protection, current limiting with foldback
