DESCRIPTION
The LT®3050 is a micro-power, low noise, low dropout voltage (LDO) linear regulator. The device supplies 100mA of output current with a dropout voltage of 340mV. A 10nF bypass capacitor reduces output noise to 30μVRMS in a 10Hz to 100kHz bandwidth and soft-starts the reference. The LT3050’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.
