L4993MD Datasheet PDF - ST Microelectronics

●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)
