The LT ? 1964 is a micropower low noise, low dropout nega-
tive regulator. The device is capable of supplying 200mA
of output current with a dropout voltage of 340mV. Low
quiescent current (30μA operating and 3μA shutdown)
makes the LT1964 an excellent choice for battery-pow-
ered applications. Quiescent current is well controlled in
dropout.
Other features of the LT1964 include low output noise.
With the addition of an external 0.01μF bypass capacitor,
output noise is reduced to 30μV RMS over a 10Hz to 100kHz
bandwidth. The LT1964 is capable of operating with small
capacitors and is stable with output capacitors as low
as 1μF. Small ceramic capacitors can be used without
the necessary addition of ESR as is common with other
APPLICATIONS
regulators. Internal protection circuitry includes reverse
output protection, current limiting, and thermal limiting.
