FEATURES LT3055 Series
500mA, Linear Regulator
with Precision Current Limit
and Diagnostics
DESCRIPTION n n n n n n The LT®3055 series are micropower, low noise, low dropout
voltage (LDO) linear regulators. The devices supply 500mA
of output current with a dropout voltage of 350mV. A 10nF
bypass capacitor reduces output noise to 25μVRMS in a
10Hz to 100kHz bandwidth and soft starts the reference.
The LT3055’s ±45V input voltage rating combined with its
precision current limit and diagnostic functions make the
IC an ideal choice for robust, high reliability applications. n n n n n n Output Current: 500mA
