L4995 Automotive 5V, 500mA low drop voltage regulator Datasheet - production data Wide temperature range (Tj = -40 C to 150 C) Enable input for enabling/disabling the voltage regulator PowerSSO-12 PowerSSO-24 Description L4995 is a family of monolithic integrated 5 V Features voltage regulators with a low drop voltage at currents of up to 500 mA, available in both 12 and Max DC supply voltage V 40V S 24 pin packages. Max output voltage tolerance V +/-2% o The output voltage regulating element consists of Max dropout voltage V 500mV dp a p-channel MOS and regulation is performed Output current I 500mA regardless of input voltage transients of up to 40V. o (1) Quiescent current I 3A qn The high precision of the output voltage is obtained using a pre-trimmed reference voltage. 1. Typical value with regulator disabled The L4995 family is protected against short circuit and overtemperature protection switches off the AEC-Q100 qualified devices in the case of extremely high power Operating DC supply voltage dissipation. The L4995 integrates the watchdog, range 5.6 V to 31 V enable and externally programmable reset Low dropout voltage circuits. The L4995A features the externally programmable reset and enable. Finally the Low quiescent current consumption L4995R features the externally programmable Reset circuit sensing of output voltage down to reset. 1 V The combination of such features makes this Programmable reset pulse delay with external device particularly flexible and suitable to supply capacitor microprocessor systems in automotive Programmable watchdog timer with external applications. capacitor Thermal shutdown and short circuit protection Table 1.
