YB1210R 300mA, Ultra-Low-Noise, High PSRR LDO Regulator „ Description „ Features High Accuracy Output Voltage : ± 2% Wide Output Voltage Range : 1.2 ~ 3.6V Ultra-Low-Noise Low-Drop-Out Typical Output Current : 300 mA Low Quiescent Current: ~60μA 320mV Dropout at 300mA 3.3V Output Stable with 1.0μF Ceramic Capacitor Only Need Input and Output Capacitors Thermal Protection Shutdown Output Short-Circuit Current Limit Built-In Internal Soft-Start Green Package (RoHS) Available The YB1210R is a series of ultra-low-noise, low dropout (LDO) linear regulators with 2.0% output voltage accuracy. The YB1210R regulators achieve a low 320mV dropout at 300mA load current of 3.3V output and are available in voltages ranging from 1.2V to 3.6V with 0.1 V per step (custom voltage is considerable at request). The YB1210R regulators are optimized to work with low-ESR and low cost ceramic capacitors, reducing the amount of board space critical in portable devices. The YB1210R requires only 1.0μF 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 YB1210R regulators are available in SOT-23 / SOT-25 / SOT-89 packages. „ „ „ „ „ „ „ „ „ „ „ „ „ Applications PDA, Notebook, PC Computers DSC, Handset Camera Modules PCMCIA Cards, PC Cameras USB Based Portable Devices GSM/GPRS/3G RF Transceiver Wireless LANs Bluetooth Portable Radios Battery-Powered Devices „ „ „ „ „ „ „ „ Typical Application Circuit Figure 1-1: SOT-25 Application Circuit YB1210R Rev.1.6 Figure 1-2: SOT-23/SOT-89 Application Circuit 1 www.yobon.com.tw YB1210R 300mA, Ultra-Low-Noise, High PSRR LDO Regulator Pin Configuration Figure 2: Pin Configuration Pin Description Table 1 Name VIN GND EN N.C. or BYPASS VOUT Description Unregulated input supply.
