Function Block Diagram VOUT VCC OCP R1 - OTP GND Bandgap R2 Reference Operation The RT9076 is a high input voltage linear regulator Current Limit specifically designed to minimize external components. The RT9076 provides a current limit function to prevent damage during output over-load or shorted-circuit The minimum required output capacitance for stable conditions. The output current is detected by an internal operation is 1F effective capacitance after consideration sensing transistor. of the temperature and voltage coefficient of the capacitor. Over-Temperature Protection Output Transistor The over-temperature protection function will turn off the The RT9076 includes a built-in low on-resistance P-MOSFET when the internal junction temperature P-MOSFET output transistor for low dropout voltage exceeds 150C (typ.) and the output current exceeds applications. 30mA. Once the junction temperature cools down by Error Amplifier approximately 20C, the regulator will automatically resume operation. The Error Amplifier compares the output feedback voltage from an internal feedback voltage divider to an internal reference voltage and controls the P-MOSFET s gate voltage to maintain output voltage regulation.
