LT3013B 250mA, 4V to 80V Low Dropout Micropower Linear Regulator with PWRGD FEATURES DESCRIPTION The LT 3013B is a high voltage, micropower low dropout n Wide Input Voltage Range: 4V to 80V linear regulator. The device is capable of supplying 250mA n Low Quiescent Current: 65A of output current with a dropout voltage of 400mV. De- n Low Dropout Voltage: 400mV signed for use in battery-powered or high voltage systems, n Output Current: 250mA the low quiescent current (65A operating) makes the n No Protection Diodes Needed LT3013B an ideal choice. Quiescent current is also well n Adjustable Output from 1.24V to 60V controlled in dropout. n Stable with 3.3F Output Capacitor n Stable with Aluminum, Tantalum or Ceramic Other features of the LT3013B include a PWRGD ag to Capacitors indicate output regulation. The delay between regulated n Reverse-Battery Protection output level and ag indication is programmable with n No Reverse Current Flow from Output to Input a single capacitor. The LT3013B also has the ability to n Thermal Limiting operate with very small output capacitors. The regulator n Thermally Enhanced 16-Lead TSSOP and 12-Pin is stable with only 3.3F on the output while most older (4mm 3mm) DFN Package devices require between 10F and 100F for stability. Small ceramic capacitors can be used without any need for series resistance (ESR) as is common with other APPLICATIONS regulators. Internal protection circuitry includes reverse- n battery protection, current limiting, thermal limiting and Low Current High Voltage Regulators n reverse-current protection. Regulator for Battery-Powered Systems n Telecom Applications The device is available with an adjustable output with a n Automotive Applications 1.24V reference voltage.
