Gesamt 11 Seiten YB1231 HV600mA, Low-Noise LDO Regulator „ Description 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 2.2μF output capacitor for stability with any load and consumes less than 1μA in shutdown mode. 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. „ Features „ 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 : 600mA „ 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 „ 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 „ Bluetooth Portable Radios Typical Application Circuit Figure 1-1: SOT-25 Application Circuit Figure 1-2: SOT-23/SOT-89 Application Circuit YB1231 Rev.1.6 www.yobon.com.tw 1 YB1231 HV600mA, Low-Noise LDO Regulator Shutdown Exit Delay Shutdown Delay Output Voltage vs. Temperature Output Noise Measurement Line Transient Response (10mA) PSRR vs. Frequency YB1231 Rev.1.6 www.yobon.com.tw 6 6 Page
