DESCRIPTION

This circuit combines both a filter and a voltage regulator in order to provide a high ripple rejection over a wide input voltage range.

Asupervisor low-pass loop of the element prevents the output transistor from saturation at low input voltage.

The non linear behaviour of this control circuitry allows a fast settling of the filter.

■ OUTPUT VOLTAGE ADJUSTABLE FROM 4 TO 11V

■ HIGH OUTPUT CURRENT (up to 250mA)

■ HIGH RIPPLE REJECTION

■ HIGH LOAD REGULATION

■ HIGH LINE REGULATION

■ SHORT CIRCUIT PROTECTION

■ THERMAL SHUT DOWN WITH HYSTERESIS

■ DUMP PROTECTION
