... A operating and shut- down) makes the LT3010 an ideal choice. Quiescent current is also well controlled in dropout. Other features of the LT3010 include the ability to operate with very small output capacitors. The regulators are stable with only the output while most older devices require between 10 F and 100 F for stability ...

... Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired. Note 2: The LT3010 (adjustable version) is tested and specified for these conditions with the ADJ pin connected to the OUT pin. Note 3: Operating conditions are limited by maximum junction temperature ...

... IN pin with respect to ground and the OUT pin. In the case of a reversed input, which can happen if a battery is + LOAD plugged in backwards, the LT3010 will act as if there is a diode in series with its input. There will be no reverse current flow into the LT3010 and no reverse voltage will 3010 F01 appear at the load ...

... At V OUT (12V/1.275V) • (–10mV) = –94mV Output Capacitance and Transient Response The LT3010 is designed to be stable with a wide range of output capacitors. The ESR of the output capacitor affects stability, most notably with small capacitors. A minimum output capacitor with an ESR of 3 recommended to prevent oscillations ...

... LT3010/LT3010 APPLICATIO S I FOR ATIO The LT3010 series regulators have internal thermal limit- ing designed to protect the device during overload condi- tions. For continuous normal conditions the maximum junction temperature rating of 125 C must not be ex- ceeded important to give careful consideration to all sources of thermal resistance from junction to ambient ...

... Protection Features The LT3010 incorporates several protection features which make it ideal for use in battery-powered circuits. In addi- tion to the normal protection features associated with monolithic regulators, such as current limiting and ther- mal limiting, the device is protected against reverse-input voltages, and reverse voltages from output to input ...
