TC1054
PRELIMINARY INFORMATION
TC1054-01 6/12/97
50mA CMOS LDO WITH SHUTDOWN
AND ERROR OUTPUT
GENERAL DESCRIPTION
The TC1054 is a high accuracy (typically
±
0.5%) CMOS
upgrade for older (bipolar) low dropout regulators. De-
signed specifically for battery-operated systems, the
TC1054’s CMOS construction eliminates wasted ground
current, significantly extending battery life. Total supply
current is typically 50
μ
A at full load (20 to 60 times lower
than in bipolar regulators).
TC1054 key features include ultra low noise operation,
very low dropout voltage (typically 100mV at full load) and
internal feed-forward compensation for fast response to
step changes in load. An error output (ERROR) is asserted
when the TC1054 is out-of-regulation (due to a low input
voltage or excessive output current). ERROR can be used
as a low battery warning or as a processor RESET signal
(with the addition of an external RC network). Supply current
is reduced to less than 1
μ
A, and both V
OUT
and ERROR
are disabled when the shutdown input is low. The TC1054
incorporates both over-temperature and over-current pro-
tection.
The TC1054 is stable with an output capacitor of only
1
μ
F and has a maximum output current of 50mA. For higher
output current regulators, please see the TC1055
(I
OUT
= 100mA) regulator and TC1107, TC1108 (I
OUT
=
300mA) data sheets.
