Function Block Diagram

Operation

The RT9058 is a high input voltage linear regulator

specifically designed to minimize external components.

The input voltage range is from 3.5V to 36V.

Output Transistor

The RT9058 includes a built-in low on-resistance

P-MOSFET output transistor for low dropout voltage

applications.

Error Amplifier

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.

Current Limit Protection

The RT9058 provides a current limit function to prevent

damage during output over-load or shorted-circuit

conditions. The output current is detected by an internal

sensing transistor.

Over Temperature Protection

The over temperature protection function will turn off the

P-MOSFET when the internal junction temperature

exceeds 150

°C (typ.) and the output current exceeds 4mA.

Once the junction temperature cools down by

approximately 20

°C, the regulator will automatically

resume operation.
