1 / 12 page  RT9014/A Preliminary 1 DS9014/A-08 August 2007 www.richtek.com Ordering Information General Description RT9014/A is a dual channel, low noise, and low dropout with the sourcing ability up to 300mA, an open drain driver and power-on reset function. The open-drain output is capable of sinking 150mA for LED backlighting applications. The range of output voltage is from 1.2V to 3.6V by operating from 2.5V to 5.5V input. RT9014/A offers 2% accuracy, extremely low dropout voltage (240mV @ 300mA), and extremely low ground current, only 27 μA per LDO. The shutdown current is near zero current which is suitable for battery-power devices. Other features include current limiting, over temperature, output short circuit protection. RT9014/A is short circuit thermal folded back protected. RT9014/A lowers its OTP trip point from 165 °C to 110°C when output short circuit occurs (VOUT < 0.4V) providing maximum safety to end users. RT9014/A can operate stably with very small ceramic output capacitors, reducing required board space and component cost. RT9014/A is available in fixed output voltages in the WDFN-10L 3x3 package. Features Wide Operating Voltage Ranges : 2.5V to 5.5V Low-Noise for RF Application No Noise Bypass Capacitor Required Fast Response in Line/Load Transient TTL-Logic-Controlled Shutdown Input Low Temperature Coefficient Dual LDO Outputs (300mA/300mA) 1 Open-Drain Driver Ultra-low Quiescent Current 27 μμμμμA/LDO High Output Accuracy 2% Short Circuit Protection Thermal Shutdown Protection Current Limit Protection Short Circuit Thermal Folded Back Protection Tiny 10-Lead WDFN Package RoHS Compliant and 100% Lead (Pb)-Free Applications CDMA/GSM Cellular Handsets Battery-Powered Equipment Laptop, Palmtops, Notebook Computers Hand-Held Instruments PCMCIA Cards Portable Information Appliances Note : Richtek Pb-free and Green products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020.
