8 / 12 page YB1210R 300mA, Ultra-Low-Noise, High PSRR LDO Regulator YB1210R Rev.1.6 www.yobon.com.tw 8 Function Block Figure 3: Function Block Functional Description The YB1210R is an ultra-low-noise, low-quiescent current, low-dropout linear regulator. It is supplied in a SOT-23 / SOT-25 / SOT-89 package for different applications. YB1210R can supply loads up to 300mA (typical operation, not maximum) and output voltages are preset and ranging from 1.2V to 3.6V. As shown in the Functional Block Diagram, the YB1210R consists of a reference and noise bypass circuit, error amplifier, output drive transistor, internal feedback voltage divider, thermal sensor, and short circuit current limiter. The internal reference is connected to the error amplifier’s inverting input. The error amplifier compares this reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the reference voltage, the gate of the pass-transistor is pulled low. This allows more current to pass to the output and increases the output voltage. If the feedback voltage is too high, the gate of the pass transistor is pulled high, allowing less current to pass to the output. Stability The YB1210R is a high performance LDO emphasizing stability with low output capacitance. It is able to maintain stability with an output capacitor as low as 1.0μF. The output capacitor can also be increased to optimize performance. The YB1210R will remain stable and in regulation with no load, unlike many other voltage regulators. |
