GENERAL DESCRIPTION
The TC57 is a low dropout regulator controller that
operates with an external PNP pass transistor, allowing the
user to tailor the LDO characteristics to suit the application
at hand. This results in lower dropout operation (and often
lower cost) compared with traditional linear regulators with
on-board pass transistors. The maximum output current of
a TC57-based regulator circuit is limited only by the charac-
teristics of the external pass transistor. For example, a
maximum output current of 650 mA (with a dropout voltage
of 100 mV) results when an FZT749 pass transistor is used,
while a Darlington configuration can deliver up to 4A.
Flexibility, and superior performance make this family of
regulator controllers the ideal choice in applications where
low dropout voltage and low installed cost are key.
