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.
