XC6602Series

ETR03045-007b

1A, 0.5V Low Input Voltage, High Speed LDO Regulator

■GENERAL DESCRIPTION

The XC6602 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 Nch 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). The inrush current (I_RUSH) from V_INto V_OUTfor charging C_Lat

start-up can be reduced and makes the V_INstable. The soft-start time is optimized internally.

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.
