Product Summary

The LM2576T-ADJ is a Step-Down Voltage Regulator. The LM2576T-ADJ provides all the active funtions for a step-down switching regulator. The LM2576T-ADJ features an output voltage which is adjustable from 1.23V to 37V and is capable of driving a 3A load with excellent line and load regulation. The LM2576T-ADJ offers a high efficiency replacement for popular three-terminal adjustable linear regulators. LM2576T-ADJ substantially reduces the size of the heat sink and in many cases no heat sink is required.

Parametrics

LM2576T-ADJ absolute maximum ratings: (1)maximum supply voltage: 45V; (2)on/off pin input voltage:- 0.3V~40V; (3)output voltage to ground: -1V; (4)power dissipation: internally limited; (5)storage temperature range: 65℃~150℃; (6)lead temperature: 260℃.

Features

LM2576T-ADJ features: (1)adjustable output, reference voltage ±2% max over line and load conditions; (2)guaranteed 3A output current; (3)wide input voltage range, 4V to 40V; (4)wide output voltage range,1.23V to 37V; (5)requires only 6 external components; (6)52kHz fixed frequency internal oscillator; (7)low power standby mode; (8)efficency typically over 80%; (9)uses readily available standard inductors; (10)thermal shutdown and current limit protection; (11)100% electrical thermal limit burn-in.
