The maximum input voltage is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
To ensure stability, a minimum output capacitance of 10uF is recommended, and the output capacitor should be placed as close to the output pin as possible.
The maximum output current is 150mA, but it's recommended to keep it below 100mA for optimal performance and to prevent overheating.
To reduce noise and ripple, add a 10uF capacitor in parallel with a 10nF capacitor on the output, and use a low-ESR capacitor for the output capacitor.
The thermal shutdown temperature is 150°C, and the device will automatically shut down if the junction temperature exceeds this value.
