LT3010/LT3010-5 50mA, 3V to 80V Low Dropout Micropower Linear Regulator
Wide Input Voltage Range: 3V to 80V
The LT®3010 is a high voltage, micropower low dropout n
Low Quiescent Current: 30µA
linear regulator. The device is capable of supplying 50mA n
Low Dropout Voltage: 300mV
output current with a dropout voltage of 300mV. Designed n
Output Current: 50mA
for use in battery-powered or high voltage systems, the low n
Thermally Enhanced 8-Lead MSOP Package
quiescent current (30µA operating and 1µA in shutdown) n No Protection Diodes Needed makes the LT3010 an ideal choice. Quiescent current is n Fixed Output Voltage: 5V (LT3010-5) also well controlled in dropout. n Adjustable Output from 1.275V to 60V (LT3010) Other features of the LT3010 include the ability to operate n 1µA Quiescent Current in Shutdown with very smal output capacitors. The regulators are stable n Stable with 1µF Output Capacitor with only 1µF on the output while most older devices re- n Stable with Aluminum, Tantalum or Ceramic quire between 10µF and 100µF for stability. Small ceramic Capacitors capacitors can be used without the necessary addition of n Reverse-Battery Protection ESR as is common with other regulators. Internal protec- n No Reverse Current Flow from Output tion circuitry includes reverse-battery protection, current n Thermal Limiting limiting, thermal limiting and reverse current protection.
The device is available in a fixed output voltage of 5V and as an adjustable device with a 1.275V reference voltage. n Low Current High Voltage Regulators The LT3010 regulator is available in the 8-lead MSOP pack- n Regulator for Battery-Powered Systems age with an exposed pad for enhanced thermal handling n Telecom Applications capability. n Automotive Applications L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and ThinSOT is a trademark of Linear Technology Corporation.
