DETAILED DESCRIPTION
The TC1072 and TC1073 are precision fixed output
voltage regulators. (If an adjustable version is desired,
please see the TC1070/TC1071/TC1187 data sheet.)
Unlike bipolar regulators, the TC1072 and TC1073’s
supply current does not increase with load current. In
addition, VOUT remains stable and within regulation
over the entire 0mA to IOUTMAX load current range, (an
important consideration in RTC and CMOS RAM
battery back-up applications).
Figure 3-1 shows a typical application circuit. The
regulator is enabled any time the shutdown input
(SHDN)isatorabove VIH, and shutdown (disabled)
when SHDN is at or below VIL. SHDN may be
controlled by a CMOS logic gate, or I/O port of a
microcontroller. If the SHDN input is not required, it
should be connected directly to the input supply. While
in shutdown, supply current decreases to 0.05
µA
(typical), VOUT falls to zero volts, and ERROR is open-
circuited.
FIGURE 3-1:
TYPICAL APPLICATION
CIRCUIT
3.1
ERROR Open Drain Output
ERROR is driven low whenever VOUT falls out of
regulation by more than – 5% (typical). This condition
may be caused by low input voltage, output current
limiting, or thermal limiting. The ERROR output voltage
value (e.g. ERROR =VOL at 4.75V (typ.) for a 5.0V
regulator and 2.85V (typ.) for a 3.0V regulator).
ERROR output operation is shown in Figure 3-2.
Note that ERROR is active when VOUT falls to VTH,and
inactive when VOUT rises above VTH by VHYS.
As shown in Figure 3-1, ERROR canbeusedasa
battery low flag, or as a processor RESET signal (with
the addition of timing capacitor C2). R1 x C2 should be
chosen to maintain ERROR below VIH of the processor
RESET input for at least 200 msec to allow time for the
system to stabilize. Pull-up resistor R1 can be tied to
VOUT,VIN or any other voltage less than (VIN +0.3V).

Output Capacitor
A1
µF(min) capacitor from VOUT to ground is
recommended. The output capacitor should have an
effective series resistance greater than 0.1
Ω and less
than 5.0
Ω, and a resonant frequency above 1MHz. A
1
µF capacitor should be connected from VIN to GND if
there is more than 10 inches of wire between the
regulator and the AC filter capacitor, or if a battery is
used as the power source. Aluminum electrolytic or
tantalum capacitor types can be used. (Since many
aluminum electrolytic capacitors freeze at approxi-
mately -30°C, solid tantalums are recommended for
applications operating below -25°C.) When operating
from
sources
other
than
batteries,
supply-noise
rejection and transient response can be improved by
increasing the value of the input and output capacitors
and employing passive filtering techniques.
3.3
Bypass Input
A 470pF capacitor connected from the Bypass input to
ground
reduces
noise
present
on
the
internal
reference, which in turn significantly reduces output
noise. If output noise is not a concern, this input may be
left unconnected. Larger capacitor values may be
used, but results in a longer time period to rated output
voltage when power is initially applied.
