A thermal shutdown circuit limits the junction temperature of APE8981. When the junction
temperature exceeds +160°C, a thermal sensor turns off the output NMOS, allowing the device to
cool down. The regulator regulates the output again through initiation of a new soft-start cycle
after the junction temperature cools by 40 ° C, resulting in a pulsed output during continuous
thermal overload conditions. The thermal shutdown designed.
Normally, use a MLCC capacitor on the input and output of the APE8981. Larger input
capacitor values provide better supply-noise rejection and transient response. A higher- value
output capacitor may be necessary if large, fast transients are anticipated and the device is
located several inches from the power source. The X5R and X7R type in MLCC is recommended.
For aluminum electrolytic capacitor application, 100uF in input capacitor and 220uF in output
capacitor (30mΩ < ESR < 200mΩ ) are recommended. Output capacitor of larger capacitance
can reduce noise and improve load transient response, stability, and PSRR.
The APE8981 monitors the current via the output NMOS and limits the maximum current to
prevent load and APE8981 from damages during overload or short circuit conditions.
