The S-1111/1121 Series is a positive voltage regulator with a low dropout voltage, high output voltage
accuracy, and low current consumption developed based on CMOS technology.
A built-in low on-resistance transistor provides a low dropout voltage and large output current, and a built-
in overcurrent protector prevents the load current from exceeding the current capacitance of the output
transistor. An ON/OFF circuit ensures a long battery life, and a small SOT-23-5 package realize high-
density mounting. The lineup includes the S-1111 and S-1121 Series, which differ in pin configuration.
Features
Output voltage:
1.5 V to 5.5 V, selectable in 0.1 V steps.
High-accuracy output voltage: ±1.0%
Low dropout voltage:
200 mV typ. (3.0 V output product, IOUT = 100 mA)
Low current consumption:
During operation: 35
μA typ., 65 μA max.
During shutdown: 0.1
μA typ., 1.0 μA max.
High peak current capability:
150 mA output is possible (at VIN ≥ VOUT(S) + 1.0 V)
*1
Built-in ON/OFF circuit:
Ensures long battery life.
High ripple rejection:
70 dB typ. (at 1.0 kHz)
Built-in overcurrent protector: Overcurrent of output transistor can be restricted.
Lead-free, Sn 100%, halogen-free*2
*1. Attention should be paid to the power dissipation of the package when the output current is large.
*2. Refer to “
