... The MCP201 provides a + regulated power output. The regulator uses a LDO design, is short- circuit-protected and will turn the regulator output off if it falls below 3.5V. The MCP201 also includes thermal shutdown protection. The regulator has been specifi- cally designed to operate in the automotive environ- ...

... BAT in either Ready or Ready1 mode, waiting for a CS/WAKE rising edge. The MCP201 will stay in either mode for 600 µs as the regulator powers its internal circuitry and waits until the CS/WAKE pin transitions high. During the 600 µs delay, the MCP201 will not recognize a CS/WAKE event ...

... After a thermal recovery time, the V REG short-circuit (V switched back on. The MCP201 will come up in either READY1 or READY mode and will have to be transitioned to Operational mode to re-enable data transmission. The accuracy of the voltage regulator, when using a pass transistor, will degrade due to the extra external components needed ...
