L4940 series
VERY LOW DROP 1.5 A REGULATORS
s PRECISE 5 V, 8.5 V, 10 V, 12 V OUTPUTS
s LOW DROPOUT VOLTAGE (500 mV typ
at 1.5A)
s VERY LOW QUIESCENT CURRENT
s THERMAL SHUTDOWN
s SHORT CIRCUIT PROTECTION
s REVERSE POLARITY PROTECTION
DESCRIPTION
The L4940 series of three terminal positive
regulators is available in TO-220 and D2PAK
package 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 battery powered
equipments, reducing consumption and
prolonging battery life. Each type employs
internal current limiting, antisaturation circuit,
thermal shut-down and safe area protection.
