LM3940IT-3.3
LM3940IT-3.3 - Brand New Texas Instruments Linear Voltage Regulators
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
Description
The Bay Linear LM3940 is a 1.25A high accuracy, low dropout voltage regulator
with only 40mV at light loads and 350mV(Typ.)@ 1.0A) and low quiescent current
of 240µA typical.
The LM3940 is designed for low voltage a application that requires lower
dropout voltage and faster transient response. This device is an excellent
choice for use in powering low voltage applications where require a lower
dropout, faster transient response to regulate from +2.5V to 3.8V supplies and
as a post regulator for switching supplies applications.
The LM3940 offers full protection against over-current faults, reversed input
polarity, reversed load insertion, and positive and negative transient
voltage. On-Chip trimming adjusts the reference voltage to 1%.
The LM3940 are offered in a 3-pin SOT-223, TO-220 & TO-263 package compatible
with other 3 terminal regulators. The LM3940 is also offer in a new LPDD (Low
Profile TO-263) package from 4.47 mm (DD) tickness down to only 1.27 mm (LPDD)
total tickness.
