Input Voltage Range: 1.6V to 45V The LT 3060 series are micropower, low dropout voltage
n
Output Current: 100mA (LDO) linear regulators that operate over a 1.6V to 45V
n
Quiescent Current: 40A input supply range. The devices supply 100mA of output

Fixed Output Voltages: 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, ity. The LT3060s quiescent current is merely 40A and
5V, 15V provides fast transient response with a minimum 2.2F
n
Output Tolerance: 2% Over Line, Load and output capacitor. In shutdown, quiescent current is less
Temperature than 1A and the reference soft-start capacitor is reset.
