LT3013 250mA, 4V to 80V Low Dropout Micropower Linear Regulator with PWRGD
FEATURES DESCRIPTION
n
Wide Input Voltage Range: 4V to 80V
The LT®3013 is a high voltage, micropower low dropout n
Low Quiescent Current: 65μA
linear regulator. The device is capable of supplying 250mA n
Low Dropout Voltage: 400mV
of output current with a dropout voltage of 400mV. Designed n
Output Current: 250mA
for use in battery-powered or high voltage systems, the low n No Protection Diodes Needed quiescent current (65μA operating and 1μA in shutdown) n Adjustable Output from 1.24V to 60V makes the LT3013 an ideal choice. Quiescent current is n 1μA Quiescent Current in Shutdown also well controlled in dropout. n Stable with 3.3μF Output Capacitor Other features of the LT3013 include a PWRGD fl ag to n Stable with Aluminum, Tantalum or Ceramic indicate output regulation. The delay between regulated Capacitors output level and fl ag indication is programmable with n Reverse-Battery Protection a single capacitor. The LT3013 also has the ability to n No Reverse Current Flow from Output to Input operate with very small output capacitors. The regulator n Thermal Limiting is stable with only 3.3μF on the output while most older n Thermally Enhanced 16-Lead TSSOP and devices require between 10μF and 100μF for stability. 12-Pin (4mm × 3mm) DFN Package 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- battery protection, current limiting, thermal limiting and n Low Current High Voltage Regulators reverse current protection. n 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. The LT3013 regulator is available in the thermally enhanced 16-lead TSSOP and the low profi le (0.75mm), 12-pin (4mm × 3mm) DFN package, both providing excellent thermal characteristics. , LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
