CAT6243:1.0 A Adjustable Output CMOS Linear Voltage Regulator

The 300 mA CMOS Dual LDO CAT6243 combines in a single TSOT-23 6-lead package two low dropout regulators (LDO), each with its own enable pin. The regulator outputs drive loads up to 300 mA. By design, the dual LDO provides fast response time during load current and line voltage changes. Each LDO is optimized for low noise and high crosstalk isolation. With zero shut down current and a low quiescent current of 100 µA, the dual LDO is ideal for battery operated devices with supply voltage from 2.3 V to 5.5 V. The dual LDO offers 1% initial accuracy and very low dropout voltage, typical 210 mV at 300 mA. Stable operation is provided with small 1 µF ceramic output capacitors, reducing required board space and component cost. Other features include fold-back current limit and thermal protection. The dual LDO is available in the tiny 6-lead TSOT-23 package with a maximum height of 0.8 mm.
