TC1223/TC1224
50mA and 100mA CMOS LDOs with Shutdown
Features
General Description
• Extremely Low Ground Current for Longer Battery
Life
• Very Low Dropout Voltage
• Choice of 50mA and 100mA Output (TC1223,
TC1224, Respectively)
• High Output Voltage Accuracy
• Standard or Custom Output Voltages
• Power Saving Shutdown Mode
• Over Current and Over Temperature Protection
• Space-Saving 5-Pin SOT-23A Package
• Pin Compatible Upgrades for Bipolar Regulators
The TC1223 and TC1224 are high accuracy (typically
±0.5%) CMOS upgrades for older (bipolar) low dropout
regulators such as the LP2980. Designed specifically
for battery-operated systems, the devices’ CMOS
construction eliminates wasted ground current,
significantly extending battery life. Total supply current
is typically 50A at full load (20 to 60 times lower than
in bipolar regulators).

Linear Post-Regulators for SMPS
Pagers
The devices’ key features include ultra low noise
operation; very low dropout voltage (typically 85mV,
TC1223 and 180mV, TC1224 at full load) and fast
response to step changes in load. Supply current is
reduced to 0.5A (max) and VOUT falls to zero when
the shutdown input is low. The devices incorporate both
over temperature and over current protection.
The TC1223 and TC1224 are stable with an output
capacitor of only 1F and have a maximum output
current of 50mA and 100mA respectively. For higher
output current versions, please see the TC1107,
TC1108 and TC1173 (IOUT = 300mA) data sheets.

VR is the regulator output voltage setting. For example: VR = 2.5V, 2.7V, 2.85V, 3.0V, 3.3V, 3.6V, 4.0V, 5.0V.
TC VOUT = (VOUTMAX – VOUTMIN) x 106
VOUT x T
Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range
from 0.1mA to the maximum specified output current. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value at a 1V
differential.
Thermal Regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding load or
line regulation effects. Specifications are for a current pulse equal to ILMAX at VIN = 6V for T = 10 msec.
The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the
thermal resistance from junction-to-air (i.e., TA, TJ, JA). Exceeding the maximum allowable power dissipation causes the device to initiate
thermal shutdown. Please see Section 4.0 Thermal Considerations for more details.
Apply for Junction Temperatures of -40°C to +85°C.
The minimum VIN has to justify the conditions: VIN  VR + VDROPOUT and VIN  2.7V for IL = 0.1mA to IOUTMAX.

DETAILED DESCRIPTION
3.1
The TC1223 and TC1224 are precision fixed output
voltage regulators. Unlike bipolar regulators, the
TC1223 and TC1224’s supply current does not
increase with load current. In addition, VOUT remains
stable and within regulation over the entire 0mA to
IOUTMAX operating 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) is at or above 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A (typical)
and VOUT falls to zero volts.
FIGURE 3-1:
1μF
+
Battery
A 1F (min) capacitor from VOUT to ground is
recommended. The output capacitor should have an
effective series resistance greater than 0.1 and less
than 5.0, and a resonant frequency above 1MHz. A
1F 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 approximately -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.

THERMAL CONSIDERATIONS
4.1
Thermal Shutdown
Integrated thermal protection circuitry shuts the
regulator off when die temperature exceeds 160°C.
The regulator remains off until the die temperature
drops to approximately 150°C.
4.2
Equation 4-1 can be used in conjunction with Equation
4-2 to ensure regulator thermal operation is within
limits. For example:
Given:
VINMAX
ILOADMAX = 40mA
Power Dissipation
The amount of power the regulator dissipates is
primarily a function of input and output voltage, and
output current. The following equation is used to
calculate worst case actual power dissipation:
EQUATION 4-1:
PD  (VINMAX – VOUTMIN)ILOADMAX
Where:
PD
VINMAX
VOUTMIN
ILOADMAX
= 3.0V ±10%
VOUTMIN = 2.7V – 2.5%
TJMAX
= 125°C
TAMAX
= 55°C
Find: 1. Actual power dissipation
2. Maximum allowable dissipation
Actual power dissipation:
PD  (VINMAX – VOUTMIN)ILOADMAX
= [(3.0 x 1.1) – (2.7 x .975)]40 x 10–3
= 26.7mW
Maximum allowable power dissipation:
= Worst case actual power dissipation
= Maximum voltage on VIN
= Minimum regulator output voltage
= Maximum output (load) current
PDMAX = (TJMAX – TAMAX)
JA
= (125 – 55)
220
= 318mW
The maximum allowable power dissipation (Equation
4-2) is a function of the maximum ambient temperature
(TAMAX), the maximum allowable die temperature
(TJMAX) and the thermal resistance from junction-to-air
(JA). The 5-Pin SOT-23A package has a JA of
approximately 220°C/Watt.
In this example, the TC1223 dissipates a maximum of
26.7mW; below the allowable limit of 318mW. In a
similar manner, Equation 4-1 and Equation 4-2 can be
used to calculate maximum current and/or input
voltage limits.
EQUATION 4-2:
4.3
PDMAX = (TJMAX – TAMAX)
JA
Where all terms are previously defined.
 2002-2012 Microchip Technology Inc.
Layout Considerations
The primary path of heat conduction out of the package
is via the package leads. Therefore, layouts having a
ground plane, wide traces at the pads, and wide power
supply bus lines combine to lower JA and therefore
increase the maximum allowable power dissipation
limit.
