Technical Attributes
DESCRIPTIONThe LT ®1529/LT1529-3.3/LT1529-5 are 3A low dropout regulators with micropower quiescent current and shutdown. The devices are capable of supplying 3A of output current with a dropout voltage of 0.6V. Designed for use in battery-powered systems, the low quiescent current, 50µA operating and 16µA in shutdown, make them an ideal choice. The quiescent current is well controlled; it does not rise in dropout as it does with many other low dropout PNP regulators.Other features of the LT1529 /LT1529-3.3/LT1529-5 include the ability to operate with small output capacitors. They are 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, enhancing manufacturabiltiy. Also the input may be connected to voltages lower than the output voltage, including negative voltages, without reverse current flow from output to input. This makes the LT1529/LT1529-3.3/LT1529-5 ideal for backup power situations where the output is held high and the input is at ground or reversed. Under these conditions, only 16µA will flow from the OUTPUT pin to ground. The devices are available in 5-lead TO-220 and 5-lead DD packages.FEATURES■ Dropout Voltage: 0.6V at IOUT = 3A■ Output Current: 3A■ Quiescent Current: 50µA■ No Protection Diodes Needed■ Adjustable Output from 3.8V to 14V■ 3.3V and 5V Fixed Output Voltages■ Controlled Quiescent Current in Dropout■ Shutdown IQ = 16µA■ Stable with 3.3µF Output Capacitor■ Reverse Battery Protection■ No Reverse Current■ Thermal LimitingAPPLICATIONS■ High Efficiency Regulator■ Regulator for Battery-Powered Systems■ Post Regulator for Switching Supplies■ 5V to 3.3V Logic Regulator
