Linear Tech LT3055MPMSE#PBF LDO Regulator MSOP 16 Pin

The LT3055 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 25μV RMS 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. A single resistor programs the LT3055’s current limit, accurate to ±10% over a wide input voltage and temperature range. Another resistor programs the LT3055’s minimum output current monitor, useful for detecting open-circuit conditions. The current monitor function sources a current equal to 1/500th of output current. Logic fault pins assert low if the LT3055 is in current limit (FAULT2), operating below its minimum output current (FAULT1) or is in thermal limit (both FAULT1 and FAULT2). PWRGD indicates output regulation. The TEMP pin indicates average die temperature. The LT3055 optimizes stability and transient response with low ESR ceramic capacitors, requiring a minimum of 3.3μF. Internal protection circuitry includes current limiting, thermal limiting, reverse battery protection, reverse current protection and reverse output protection. The LT3055 is available in fixed output voltages of 3.3V and 5V, and as an adjustable device with an output voltage range from 0.6V to 40V.
