LD1580 Datasheet 7 A Very Low Drop Positive Voltage Regulator Adjustable And Fixed

Manufacturer: STMicroelectronics

Overview: LD1580 7 A VERY LOW DROP POSITIVE VOLTAGE REGULATOR ADJUSTABLE AND FIXED PRELIMINARY DATA s s s s s s s s OUTPUT CURRENT LIMIT LOW DROPOUT VOLTAGE: TYPICALLY 400mV AT 7A OUTPUT CURRENT OUTPUT VOLTAGE REMOTE SENSE PIN FAST TRANSIENT RESPONSE THERMAL SHUTDOWN PROTECTION WITH HYSTERESIS WIDE OPERATING TEMPERATURE RANGE -40°C TO 125°C NO SUPPLY SEQUENCING PROBLEMS IN DUAL SUPPLY MODE OUTPUT VOLTAGES AVAILABLE 1.5 V, 1.8V, 2.5 V, 3.0 V, 3.3 V ADJUSTABLE.

General Description

The LD1580 is a very low dropout positive linear voltage regulator particularly suitable in applications requiring output currents up to 7 A.

The LD1580 typical dropout voltage is 400mV at 7A while it decreases at lighter loads.

This very low dropout is achieved thanks to a second input voltage pin, named VCONTROL, which is also responsable of the output power stage driving.

Key Features

  • a built-in output current limit function and a thermal shutdown protection with hysteresis which prevents from excessive power dissipation in case of insufficient.
