YB1231 – HV600mA  
Low-Noise LDO Regulator  
Features  
Description  
„ 2.0% Accuracy Output Voltage  
„ Output Voltage range 3.2V~4.5V  
„ Low-Noise Low-Drop-Out  
„ Stable with 2.2μF Ceramic Capacitor for  
Any Load  
„ Typical Output Current : 600 mA  
„ Low Quiescent Current : ~100μA  
„ 440mV Dropout at 600mA Load (4.5V)  
„ Only Need Input and Output Capacitors  
„ Power Saving Shutdown Mode (<1μA)  
„ Thermal Protection Shutdown  
„ Built-In Internal Soft-Start  
The YB1231 is a series of ultra-low-noise,  
low dropout (LDO) linear regulators with  
2.0% output voltage accuracy. The YB1231  
regulators achieve a low 440mV dropout at  
600mA load current of 4.5V output and are  
available in voltages ranging from 3.2V to  
4.5V with 0.1 V per step (custom voltage is  
considerable at request).  
The YB1231 regulators are optimized to  
work with low-ESR and low cost ceramic  
capacitors, reducing the amount of board  
space critical in hand-held devices. The  
YB1231 requires only 2.2 μF output  
capacitor for stability with any load and  
consumes less than 1μA in shutdown  
mode.  
„ Output Short-circuit Current Limit  
Protection  
„ Green package (RoHS) available  
Applications  
„ PDA, Palmtops and Notebook  
Computers  
„ DSC, Handset Camera Modules  
„ PCMCIA Cards, PC Cameras  
„ USB Based Portable Devices (MP3, PMP)  
„ GSM/GPRS/3G RF Transceiver Modules  
„ Wireless LANs  
Built-in thermal shutdown and short-circuit  
protect offer secure protection against fault  
operation. The YB1231 regulators are  
available in SOT-23 / SOT-25 / SOT-89  
packages.  
„ Bluetooth Portable Radios
