HIGH RIPPLE-REJECTION AND SMALL PACKAGE CMOS VOLTAGE REGULATOR
S-1323 Series
Rev.5.0_00
10
Seiko Instruments Inc.
Explanation of Terms
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-1323 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 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.

Line
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 (
ΔV
OUT2)
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)
