DESCRIPTION

The LM2925 features a low dropout, high current regulator.

Also included on-chip is a reset function with an externally set delay time. Upon power up, or after the

detection of anyerror in the regulated output, the reset pin remains in the ac-tive low state for the

duration of the delay.

Types of errors de-tected include any that cause the output to become unregu- lated: low input

voltage, thermal shutdown, short circuit,input transients, etc. No external pull-up resistor is neces-sary.

The current charging the delay capacitor is very low, al-lowing long delay times.

Designed primarily for automotive applications, the LM2925 and all regulated circuitry are protected

from reverse battery installations or two-battery jumps.

During line transients, such as a load dump (60V) when the input voltage to the regulator can

momentarily exceed the specified maximum operating voltage, the 0.75A regulator will automatically

shut down to protect both internal circuits and theload.

The LM2925 cannot be harmed by temporary mirror-image inser-tion.

Familiar regulator features such as short circuit and thermal overload protection are also provided.
