P-TO252-5-11

Short Functional Description

With supply voltages up to 40 V the output voltage follows a reference voltage applied at the adjust input with high accuracy. The reference voltage applied directly to the adjust input or by an e.g. external resistor divider can be V at minimum.

The output is able to drive loads up to 250 mA at minimum while they follow e.g. the 5 V output of a main voltage regulator as reference with high accuracy.

The TLE 4252 tracker can be switched into stand-by mode to reduce the current consumption to very low values. This feature makes the IC suitable for low power battery applications.

Function

Supply voltage input for battery or a pre-regulated
voltage of a e.g. DC to DC converter.

Enable input for tracker An active high signal turns on the
device, with active low the tracker is turned off.

Ground Connected to the heatsink of the package.

Adjust input for tracker Input for the reference voltage
which can be connected directly or by voltage divider to the
reference see Application Information .
