11. Description
11.1 Input / output capacitors
Linear regulators require input and output capacitors in order to maintain the regulator's loop stability. If a
0.1F capacitor is connected to the output side, the IC provides stable operation at any voltage in the practical
current region. However, increase the CL capacitance when using the IC in the low current region and low
voltage. Otherwise, the IC oscillates. The equivalent series resistance (ESR) of the output capacitor must be
in the stable operation area. However, it is recommended to use as large a value of capacitance as is practical.
The output noise and the ripple noise decrease as the capacitance value increases. ESR values vary widely
between ceramic and tantalum capacitors. However, tantalum capacitors are assumed to provide more ESR
damping resistance, which provides greater circuit stability. This implies that a higher level of circuit
stability can be obtained by using tantalum capacitors when compared to ceramic capacitors with similar
values.
Vout
The recommended value : Cin=CL=0.22F(MLCC) Iout  0.5mA.
Cin=0.22F
 0.1F
The input capacitor is necessary when the battery is discharged, the power
CL=0.22F
supply impedance increases, or the line distance to the power supply is
 0.1F
long.
This capacitor might be necessary on each individual IC even if two or more regulator ICs are used. Please
confirm the stability while mounted. The IC provides stable operation with an output side capacitor of 0.1F
(Vout  2.5V). If it is 0.1F or more over the full range of temperature, either a ceramic capacitor or tantalum
capacitor can be used without considering ESR. Please confirm stability while mounted.

Figure 2. Output voltage, Output current vs. Stable Operation Area
The above graphs show stable operation with a ceramic capacitor of 0.1uF (excluding the low current region).
If the capacitance is not increased in the low voltage, low current area, stable operation may not be achieved.
Please select the best output capacitor according to the voltage and current used. The stability of the regulator
improves if a big output side capacitor is used (the stable operation area extends.) Please use as large a
capacitance as is practical. Although operation above 150 mA has not been described, stability is equal to or
better than operation at 150 mA.

The ripple rejection characteristic depends on the characteristic and the capacitance value of the capacitor
connected to the output side. The RR characteristic of 50KHz or more varies greatly with the capacitor on
the output side and PCB pattern. If necessary, please confirm stability while operating.

11.6 On/Off Control
It is recommended to turn the regulator Off when the circuit following
Vsat
the regulator is non-operating. A design with little electric power loss
OP
REG
can be implemented. We recommend the use of the on/off control of
the regulator without using a high side switch to provide an output
On/Off Cont.
from the regulator. A highly accurate output voltage with low voltage
drop is obtained.
Because the Vcont terminal current is small, it is possible to control it directly by CMOS logic. The
PULLDOWN resistance (500k) is built into the Vcont terminal. The noise and the ripple rejection
characteristics depend on the capacitance on the Vref terminal. The ripple rejection characteristic of the low
frequency region improves by increasing the capacitance of Cnp. A standard value is Cnp=0.068F.
Increase Cnp in a design with important output noise and ripple rejection requirements. The IC will not be
damaged if the capacitor value is increased. The on/off switching speed changes depending on the Np
terminal capacitance. The switching speed slows when the capacitance is large.

The package loss is limited at the temperature that the internal temperature sensor works (about 150C).
Therefore, the package loss is assumed to be an internal limitation. There is no heat radiation characteristic of
the package unit assumed because of the small size. Heat is carried away by the device being installed on the
PCB. This value changes by the material and the copper pattern etc. of the PCB. The losses are approximately
900mW(SOT89-5). Enduring these losses becomes possible in a lot of applications operating at 25C.
Determining the thermal resistance when mounted on a PCB.
The operating chip junction temperature is shown by
Tj=ja  Pd + Ta. Tj of the IC is set to about 150C.
Pd is a value when the overtemperature sensor is made to work.
Ta (Ta=25C)
150 = ja  pd + 25
ja  Pd = 125
ja = (125/ pd) (C / mW)
Pd is easily obtained.
Mount the IC on the PCB. Pd becomes VIN  Iin when the output side of the IC is short-circuited.
The input current decreases gradually by the temperature rise of the chip.
Please use the value when the current is steady (thermal equilibrium is reached).
In many cases, heat radiation is good, and Pd becomes 900 mW or more.
Pd is obtained by the normal temperature in degrees. The current that can be used at the highest operating
temperature is obtained from the graph of the figure below.

Procedure (Do when PCB mounted).
1. Pd is obtained (VIN  Iin when the output side is
short-circuited).
2. Pd is plotted on the horizontal line to 25C.
3. Pd is connected with the point of 150C by the straight line
(bold face line).
4. A line is extended vertically above the point of use
temperature in the design. For instance, 75C is assumed
(broken line).
5. Extend the intersection of the derating curve (fat solid line)
and (broken line) to the left and read the Pd value.
The maximum current that can be used at the highest operating temperature is:
Iout  DPd  (VIN(max)  Vout).

12. Definition of term
・Output Voltage (Vout)
The output voltage is specified with VIN=(Vout(typ)+1V) and Iout=5mA.
・Maximum Output Current (Iout MAX)
The rated output current is specified under the condition where the output voltage drops 0.3V the value specified
with Iout=5mA. The input voltage is set to Vout(typ)+1V and the current is pulsed to minimize temperature effect.
・Dropout Voltage (Vdrop)
The dropout voltage is the difference between the input voltage and the output voltage at which point the regulator
starts to fall out of regulation. Below this value, the output voltage will fall as the input voltage is reduced. It is
dependent upon the load current and the junction temperature.
・Line Regulation (LinReg)
Line regulation is the ability of the regulator to maintain a constant output voltage as the input voltage changes. The
line regulation is specified as the input voltage is changed from VIN=Vout(typ)+1V to VIN=Vout(typ)+6V. It is a
pulse measurement to minimize temperature effect.
・Load Regulation (LoaReg)
Load regulation is the ability of the regulator to maintain a constant output voltage as the load current changes. It is
a pulsed measurement to minimize temperature effects with the input voltage set to VIN=Vout(typ)+1V. The load
regulation is specified output current step conditions of 5mA to 100mA.
・Ripple Rejection (R.R)
Ripple rejection is the ability of the regulator to attenuate the ripple content of the input voltage at the output.
It is specified with 200mVrms, 1kHz super-imposed on the input voltage, where VIN=Vout+1.5V. Ripple
rejection is the ratio of the ripple content of the output vs. input and is expressed in dB.
・Standby Current (Istandby)
Standby current is the current, which flows into the regulator when the output is turned off by the control function
(Vcont=0V).
・Over Current Sensor
The over current sensor protects the device when there is excessive output current. It also protects the device if the
output is accidentally connected to ground.
・Thermal Sensor
The thermal sensor protects the device in case the junction temperature exceeds the safe value (TJ=150C). This
temperature rise can be caused by external heat, excessive power dissipation caused by large input to output voltage
drops, or excessive output current. The regulator will shut off when the temperature exceeds the safe value. As the
junction temperatures decrease, the regulator will begin to operate again. Under sustained fault conditions, the
regulator output will oscillate as the device turns off then resets. Damage may occur to the device under extreme
fault.
Please reduce the loss of the regulator when this protection operate, by reducing the input voltage or make better heat
efficiency. In the case that the power, VIN  Ishort(Short Circuit Current), becomes more than twice of the maximum
rating of its power dissipation in a moment, there is a possibility that the IC is destroyed before internal thermal
protection works.
・Reverse Voltage Protection
Reverse voltage protection prevents damage due to the output voltage being higher than the input voltage. This fault
condition can occur when the output capacitor remains charged and the input is reduced to zero, or when an external
voltage higher than the input voltage is applied to the output side
