1 / 10 page CAT6218 © 2007 Catalyst Semiconductor, Inc. 1 Doc. No. MD-4010 Rev. A Characteristics subject to change without notice 300mA CMOS LDO Regulator FEATURES Guaranteed 300mA output current Low dropout voltage of 180mV typical at 300mA Stable with 1μF ceramic output capacitor External 10nF bypass capacitor for low noise Quick-start feature No-load ground current of 55μA typical Full-load ground current of 80μA typical ±1.0% output voltage initial accuracy ±2.0% accuracy over temperature “Zero” current shutdown mode Fold-back current limit and under-voltage lockout Thermal protection Thin SOT23-5 package APPLICATIONS Cellular phones Battery-powered devices Consumer Electronics DESCRIPTION The CAT6218 is a 300mA CMOS low dropout regulator that provides fast response time during load current and line voltage changes. The quick-start feature allows the use of an external bypass capacitor to reduce the overall output noise without affecting the turn-on time of just 150μs. With zero shutdown current and low ground current of 55μA typical, the CAT6218 is ideal for battery- operated devices with supply voltages from 2.3V to 5.5V. An internal under voltage lockout circuit disables the output at supply voltages under 2.1V typical. The CAT6218 offers 1% initial accuracy and low dropout voltage, 180mV typical at 300mA. Stable operation is provided with a small value ceramic capacitor, reducing required board space and compo– nent cost. Other features include fold-back current current limit and thermal protection. The device is available in the low profile (1mm max height) 5-lead thin SOT23 package.
