L4940xx

Very low drop 1.5 A regulator

Features

■ Precise 5, 8.5, 10, 12 V outputs

■ Low dropout voltage (450 mV typ. at 1 A)

■ Very low quiescent current

■ Thermal shutdown

■ Short circuit protection

■ Reverse polarity protection

Description

The L4940 series of three terminal positive

regulators is available in TO-220, TO-220FP and

D2PAK packages and with several fixed output

voltages, making it useful in a wide range of

industrial and consumer applications. Thanks to

its very low input/output voltage drop, these

devices are particularly suitable for batteries

powered equipment, reducing consumption and

prolonging battery life. Each type employs internal

current limiting, antisaturation circuit, thermal

shut-down and safe area protection.
