Description
The L4993 is a monolithic integrated 5V Voltage regulator with a low drop voltage at currents up to 150mA.The output voltage regulating element consists in a p-channel MOS and the regulation is performed regardless of input voltage transients up to 40V. The high precision of the output voltage is obtained with a pre-trimmed reference voltage.

■ Operating DC supply voltage range 5.6V to 31V
■ Reset circuit sensing the output voltage down to 1V
■ Programmable reset pulse delay with external capacitor
■ Watchdog
■ Programmable watchdog timer with external capacitor
■ Enable input for enabling/disabling the watchdog functionality
■ Thermal shutdown and short circuit protection
■ Wide temperature range (Tj = -40°C to 150°C)
