SUPER-LOW OUTPUT LOW DROPOUT
CMOS VOLTAGE REGULATOR
S-11L10 Series
S-11L10 Series, developed using the CMOS technology, is a
positive voltage regulator IC which has the low output voltage,
the high-accuracy output voltage and the low current
consumption (150 mA output current).
A 1.0 µF small ceramic capacitor can be used. It operates with
low current consumption of 9 µA typ.
The overcurrent protection circuit prevents the load current
from exceeding the capacitance of output transistor. The
power-off circuit ensures longer battery life.
Various capacitors, also small ceramic capacitors, can be used
for this IC more than for the conventional regulator ICs which
have CMOS technology.
Furthermore a small SOT-23-5 and SNT-6A(H) packages
realize high-density mounting.
Features
• Low output voltage:
0.8 V to 3.3 V, selectable in 0.05 V step.
• Low input voltage:
1.2 V to 3.65 V
• Low equivalent series resistance capacitor : Ceramic capacitor of 1.0 µF or more can be used as the I/O capacitor.
• High-accuracy output voltage:
±1.0% (0.8 V to 1.45 V output product : ±15 mV)
• Low dropout voltage:
210 mV typ. (products having the output of 1.5 V, IOUT = 100 mA)
• Low current consumption:
During operation: 9.0 µA typ., 16 µA max.
• Output current:
During power-off: 0.1 µA typ., 0.9 µA max.
Possible to output 150 mA (at VIN ≥ VOUT(S) + 1.0 V)*1
• Ripple rejection:
60 dB typ. (at 1.0 kHz, VOUT = 1.25 V)
• Built-in overcurrent protection circuit:
limits overcurrent of output transistor
• Built-in power-off circuit:
Ensures long battery life.
• Discharge shunt function

Explanation of Terms
1. Low dropout voltage regulator
This IC’s voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.
2. Output voltage (VOUT)
The accuracy of the output voltage is ensured at ±1.0% or ±15 mV*1 under the specified conditions of fixed input
voltage*2, fixed output current, and fixed temperature.
*1. Differs depending on the product.
*2. When VOUT < 1.5 V : ±15 mV, when 1.5 V ≤ VOUT : ±1.0%
Caution
If the above conditions change, the output voltage value may vary and exceed the accuracy
range of the output voltage. Refer to “ Electrical Characteristics” and “ Characteristics
(Typical Data)” for details.
3.
Line regulation
∆VOUT1
∆VIN•VOUT
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.
4. Load regulation (∆VOUT2)
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.
5. Dropout voltage (Vdrop)
Indicates the difference between input voltage VIN and the output voltage when; decreasing input voltage VIN
gradually until the output voltage has dropped out to the value of 98% of output voltage VOUT3, which is at VIN =
VOUT(S) + 1.0 V.
