LT3009 Series 3µA IQ, 20mA Low Dropout Linear Regulators FEATURESDESCRIPTION n Ultralow Quiescent Current: 3μA The LT®3009 Series are micropower, low dropout voltage n Input Voltage Range: 1.6V to 20V (LDO) linear regulators. The devices supply 20mA output n Output Current: 20mA current with a dropout voltage of 280mV. No-load quiescent n Dropout Voltage: 280mV current is 3μA. Ground pin current remains at less than n Adjustable Output (VADJ = VOUT(MIN) = 600mV) 5% of output current as load increases. In shutdown, n Fixed Output Voltages: 1.2V, 1.5V, 1.8V, 2.5V, quiescent current is less than 1μA. 3.3V, 5V The LT3009 regulators optimize stability and transient n Output Tolerance: ±2% Over Load, Line and Temperature response with low ESR ceramic capacitors, requiring a n Stable with Low ESR, Ceramic Output Capacitors minimum of only 1μF. The regulators do not require the (1μF minimum) addition of ESR as is common with other regulators. n Shutdown Current: <1μA Internal protection circuitry includes current limiting, n Current Limit Protection thermal limiting, reverse-battery protection and reverse- n Reverse-Battery Protection current protection. n Thermal Limit Protection n 8-Lead SC70 and 2mm × 2mm DFN Packages The LT3009 Series are ideal for applications that require moderate output drive capability coupled with ultralow APPLICATIONS standby power consumption. The device is available in fi xed output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5V, n and as an adjustable device with an output voltage range Low Current Battery-Powered Systems n down to the 600mV reference. The LT3009 is available in Keep-Alive Power Supplies n the 6-lead DFN and 8-lead SC70 packages.
