XC6604 - High Speed LDO Regulator

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.

XC6604 Series 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.
