9 / 12 page  YB1210R 300mA, Ultra-Low-Noise, High PSRR LDO Regulator YB1210R Rev.1.6 www.yobon.com.tw 9 Internal P-Channel Pass Transistor The YB1210R features a low impedance P-channel MOSFET pass transistor. This provides several advantages over similar designs using a PNP pass transistor, including low operating power and longer battery life. The YB1210R consumes only 60µA of quiescent current under most conditions. Output Short-Circuit Current Limit The YB1210R includes a current limiter, which monitors and controls the pass transistor’s gate voltage, limiting the output current to about 200mA, for example, in a short-circuit output situation. Shutdown The YB1210R also features a low-power active shutdown mode. It has a switch that turns off the device when disabled. This allows the output capacitor and load to discharge and de-energize the load. In the shutdown mode, the internal functional blocks, such as voltage reference and the error amplifier, are turned off completely, and the quiescent current is less than 1µA. Thermal Protection Shutdown The thermal protection shutdown function protects the device from operating in over temperature condition. When the junction temperature exceeds +160°C, the thermal sensor signals the shutdown logic, turning off the pass transistor and allowing the IC to cool down. The thermal sensor turns the pass transistor on again after the IC’s junction temperature drops to +140°C. Auto-Discharge Circuitry The YB1210R deploys a NMOS connecting between VOUT and ground. When EN pin is pulled low, the NMOS is activated by an inverted signal from EN. The charge kept on output capacitor is discharged quickly through the NMOS. It prevents the system from abnormal operation at the beginning of shutdown mode. Soft-Start Circuitry The YB1210R includes a soft-start circuitry to limit inrush current at turn-on. During power up, the output capacitor and output load are charged with a reduced output current. Shortly after the initial power up, the soft-start feature is terminated and normal operation is resumed. Application Information Enable/Shutdown The YB1210R comes with an active-high enable pin that allows the regulator to be enabled. Forcing the enable pin low disables the regulator and puts it into the shutdown mode. This pin cannot be left floating as it may cause an undetermined state. Input/Output Capacitor It is recommended to use a 1.0µF capacitor on the YB1210R input and a 1.0µF capacitor on the output. For high regulation performance, larger input capacitor values and lower ESRs provide better noise rejection and line-transient response. The output noise, load-transient response, stability, and power-supply rejection can be improved by using large output capacitors. Low ESR ceramic capacitors provide optimal performance and save space. |
