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

characteristics of the external pass transistor. For
example, a maximum output current of 650mA (with a
dropout voltage of 100mV) results when an FZT749
pass transistor is used, while a Darlington configuration
can deliver up to 4A.
