LD3985 Datasheet PDF - ST Microelectronics

DESCRIPTION

●The LD3985 provides up to 150mA, from 2.5V to 6V input voltage. The ultra low drop-voltage, low quiescent current and low noise make it suitable for low power applications and in battery powered systems.

●■ INPUT VOLTAGE FROM 2.5V TO 6V

●■ STABLE WITH LOW ESR CERAMIC CAPACITORS

●■ ULTRA LOW DROPOUT VOLTAGE (100mV TYP. AT 150mA LOAD, 0.4mV TYP. AT 1mA LOAD)

●■ VERY LOW QUIESCENT CURRENT (85µA TYP. AT NO LOAD, 170µA TYP. AT 150mA LOAD; MAX 1.5µA IN OFF MODE)

●■ GUARANTEED OUTPUT CURRENT UP TO 150mA

●■ WIDE RANGE OF OUTPUT VOLTAGE: 1.25V; 1.35; 1.5; 1.8V; 2V; 2.1V; 2.2V; 2.4V; 2.5V; 2.6V; 2.7V; 2.8V; 2.85V; 2.9V; 3V; 3.1V;

●3.2V; 3.3V; 4.7V; 5V

●■ FAST TURN-ON TIME: TYP. 200µs [CO=1µF, CBYP= 10nF AND IO=1mA]
