Selection of Input and Output Capacitors (CIN, CL)
The S-1701 Series requires an output capacitor between the VOUT and VSS pins for phase compensation. A ceramic
capacitor with a capacitance of 1.0
μF or more provides a stable operation in all temperature ranges. When using an OS
capacitor, tantalum capacitor, or aluminum electrolytic capacitor, a capacitor with a capacitance of 1.0
μF or more and an
ESR of 10
Ω or less is required.
The output overshoot and undershoot values, which are transient response characteristics, vary depending on the output
capacitor value. The required capacitance value for the input capacitor differs depending on the application.
The recommended application values are CIN = 1.0
μF or more and CL = 1.0 μF or more, however, perform thorough
evaluation using the actual device, including evaluation of temperature characteristics.
Explanation of Terms
Regulator block
1. Low dropout voltage regulator
The low dropout voltage regulator is a voltage regulator whose dropout voltage is low due to its built-in low on-
resistance transistor.
2. Low ESR
A capacitor whose ESR (Equivalent Series Resistance) is low. The S-1701 Series enables use of a low ESR capacitor,
such as a ceramic capacitor, for the output-side capacitor (CL). A capacitor whose ESR is 10
Ω or less can be used.
3. Output voltage (VOUT)
The accuracy of the output voltage is ensured at
±1.0% under the specified conditions of fixed input voltage
*1, fixed
output current, and fixed temperature.
*1. Differs depending on the product.
Caution If the above conditions change, the output voltage value may vary and exceed the accuracy range of
the output voltage. Please see the electrical characteristics and attached characteristics data for
details.
4. Line regulation
ΔVOUT1
ΔVINVOUT
Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output
voltage changes due to a change in the input voltage with the output current remaining unchanged.
5. Load regulation (
ΔVOUT2)
Indicates the dependency of the output voltage on the output current. That is, the values show how much the output
voltage changes due to a change in the output current with the input voltage remaining unchanged.
6. Dropout voltage (Vdrop)
Indicates the difference between the input voltage VIN1, which is the input voltage (VIN) at the point where the output
voltage has fallen to 98% of the output voltage value VOUT3 after VIN was gradually decreased from VIN = VOUT(S)
+ 1.0
V, and the output voltage at that point (VOUT3
× 0.98).
Vdrop = VIN1
(VOUT3 × 0.98)
