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:

• Low current consumption:

210 mV typ. (products having the output of 1.5 V, IOUT = 100 mA)

During operation: 9.0 µA typ., 16 µA max.

• Output current:

• Ripple rejection:

• Built-in overcurrent protection circuit:

During power-off: 0.1 µA typ., 0.9 µA max.

Possible to output 150 mA (at VIN ≥ VOUT(S) + 1.0 V)*1

60 dB typ. (at 1.0 kHz, VOUT = 1.25 V)

limits overcurrent of output transistor

• Built-in power-off circuit:

Ensures long battery life.

• Discharge shunt function

• Selectable constant current source pull-down

• Small package:

SOT-23-5, SNT-6A(H)

• Lead-free product

*1. Attention should be paid to the power dissipation of the package when the output current is large.

„ Applications

• Power supply for battery-powered devices

• Power supply for mobile phones

• Power supply for portable equipment
