XC6604Series

ETR03071-002

0.5V Low Input, 1A High Speed LDO Regulator with Adjustable Current Limit

■GENERAL DESCRIPTION

The XC6604 series is a low voltage input (0.5V) operation and provides high accuracy ±15mV / ±20mV and can supply large

current efficiently due to its ultra low on-resistance even at low output voltages.

The series is ideally suited to the applications which require high current in low input/output voltages and consists of a N-ch

driver transistor, a voltage reference, an error amplifier, a current limiter, a fold-back circuit, a thermal shutdown (TSD) circuit, an

under voltage lock out (UVLO) circuit, a soft-start circuit and a phase compensation circuit.

Output voltage is selectable in 0.1V increments within a range of 0.5V to 1.8V using laser trimming technology and ceramic

capacitors can be used for the output stabilization capacitor (C_L). When the output current reaches the current limit, the output

voltage drops as well as the output current is decreased as a function of the foldback circuit. The current limit can be

adjustable with connecting a resistor to the I_LIMpin.

The CE function enables the output to be turned off and the series to be put in stand-by mode resulting in greatly reduced

power consumption. At the time of entering the stand-by mode, the series enables the electric charge at the output capacitor

(C_L) to be discharged via the internal switch. As a result the V_OUTpin quickly returns to the V_SSlevel.

The CE pull-down function keeps the IC to be in stand-by mode even if the CE pin is left open.
