Description
General part information
LT3012B Series
The LT3012 is a high voltage, micropower low dropout linear regulator. The device is capable of supplying 250mA of output current with a dropout voltage of 400mV. Designed for use in battery-powered or high voltage systems, the low quiescent current (40µA operating and 1µA in shutdown) makes the LT3012 an ideal choice. Quiescent current is also well controlled in dropout.Other features of the LT3012 include the ability to operate with very small output capacitors. The regulator is stable with only 3.3µF on the output while most older devices require between 10µF and 100µF for stability. Small ceramic capacitors can be used without any need for series resistance (ESR) as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection.The device is available with an adjustable output with a 1.24V reference voltage. The LT3012 regulator is available in the 16-lead TSSOP and 12 pin low profile (0.75mm) (4mm × 3mm) DFN packages with an exposed pad for enhanced thermal handling capability.Shutdown PinLT3012YesLT3012BNoAPPLICATIONSLow Current High Voltage RegulatorsRegulator for Battery-Powered SystemsTelecom ApplicationsAutomotive Applications
