LT3055HMSE-3.3#PBF

LINEAR TECHNOLOGY LT3055HMSE-3.3#PBF Fixed LDO Voltage Regulator, 1.8V to 45V In, 350mV Dropout, 3.3V/500mA Out, MSOP-16

The is a 3.3V fixed output low noise low-dropout LDO Linear Regulator. The device 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 device ±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 device current limit, accurate to ±10% over a wide input voltage and temperature range. Another resistor programs the device 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 device is in current limit, operating below its minimum output current or is in thermal limit. PWRGD indicates output regulation. The TEMP pin indicates average die temperature.
