The S-818 Series is a positive voltage regulator developed by CMOS technology and featured by low dropout

voltage, high output voltage accuracy and low current consumption.

Figure 10

Caution The above connection diagram and constant will not guarantee successful operation.

Perform through evaluation using the actual application to set the constant.

 Explanation of Terms

1. Low dropout voltage regulator

This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.

2. Output voltage (V_OUT

)

The accuracy of the output voltage is ensured at 2.0 % under the specified conditions of input voltage,

output current, and temperature, which differ product by product.

Caution When the above conditions are changed, the output voltage may vary and go out of the

accuracy range of the output voltage. Refer to the “ Electrical Characteristics” and

“ Characteristics (Typical Data)” for details.

3. Line regulation 1 (V_OUT1) and Line regulation 2 (V_OUT2

)

Line regulation indicates the input voltage dependence of the output voltage. The value shows how

much the output voltage changes due to the change of the input voltage when the output current is kept

constant.

Load regulation indicates the output current dependence of output voltage. The value shows how much

the output voltage changes due to the change of the output current when the input voltage is kept

constant.

5. Dropout voltage (V_drop

 Operation

1. Basic operation

Figure 12 shows the block diagram of the S-818 Series.

The error amplifier compares the reference voltage (V_ref) with feedback voltage (V_fb), which is the output

voltage resistance-divided by feedback resistors (R_sand R_f). It supplies the gate voltage necessary to

maintain the constant output voltage which is not influenced by the input voltage and temperature change,

to the output transistor.

2. Output transistor

In the S-818 Series, a low on-resistance P-channel MOS FET is used as the output transistor.

Be sure that V_OUTdoes not exceed V_IN0.3 V to prevent the voltage regulator from being damaged due

to reverse current flowing from VOUT pin through a parasitic diode to the VIN pin, when the potential

of V_OUTbecame higher than V_IN.

12

LOW DROPOUT CMOS VOLTAGE REGULATOR

S-818 Series

Rev.3.1^_02

3. ON/OFF pin

This pin starts and stops the regulator.

When the ON/OFF pin is set to OFF level, the entire internal circuit stops operating, and the built-in P-

channel MOS FET output transistor between the VIN pin and the VOUT pin is turned off, reducing

current consumption significantly. The VOUT pin becomes the V_SSlevel due to the internally divided

resistance of several M between the VOUT pin and the VSS pin.

The structure of the ON/OFF pin is shown in Figure 13. Since the ON/OFF pin is neither pulled down

nor pulled up internally, do not use it in the floating status. In addition, note that the current consumption

increases if a voltage of 0.3 V to V_IN– 0.3 V is applied to the ON/OFF pin. When not using the ON/OFF

pin, connect it to the VIN pin in the product A type, and connect it to the VSS pin in B type.

 Selection of Output Capacitor (C_L)

The S-818 Series needs an output capacitor between the VOUT pin and the VSS pin for phase

compensation. A small ceramic or an OS electrolyte capacitor of 2 F or more can be used. When a

tantalum or an aluminum electrolyte capacitor is used, the capacitance must be 2 F or more and the

ESR must be 10  or less.

Attention should be paid not to cause an oscillation due to increase of ESR at low temperatures when

an aluminum electrolyte capacitor is used.

Evaluate the performance including temperature characteristics before prototyping the circuit.

Overshoot and undershoot characteristics differ depending upon the type of the output capacitor. Refer

to the C_Ldependence data in “ Transient Response Characteristics (S-818A30A, Typical data,

Ta=25°C)”.

 Precautions

 Wiring patterns for the VIN pin, the VOUT pin and GND should be designed so that the impedance is

low. When mounting an output capacitor between the VOUT pin and the VSS pin (C_L) and a capacitor

for stabilizing the input between the VIN pin and the VSS pin (C_IN), the distance from the capacitors to

these pins should be as short as possible.

 Note that generally the output voltage may increase when a series regulator is used at low load current

(10 mA or less).

 Generally a series regulator may cause oscillation, depending on the selection of external parts. The

following conditions are recommended for the S-818 Series. However, be sure to perform sufficient

evaluation under the actual usage conditions for selection, including evaluation of temperature

characteristics.

Input capacitor (C_IN):

Output capacitor (C_L):

0.47F or more

2 F or more

Equivalent series resistance (ESR): 10  or less

Input series resistance (R_IN): 10  or less

 The voltage regulator may oscillate when the impedance of the power supply is high and the input

capacitor is small or an input capacitor is not connected.

 Overshoot may occur in the output voltage momentarily if the voltage is rapidly raised at power-on or

when the power supply fluctuates. Sufficiently evaluate the output voltage at power-on with the actual

device.

 The application conditions for the input voltage, the output voltage, and the load current should not

exceed the package power dissipation.

 Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in

electrostatic protection circuit.

 In determining the output current, attention should be paid to the output current value specified in Table

5 in the “ Electrical Characteristics” and footnote *5 of the table.

 ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement

by products including this IC of patents owned by a third party.
