Overview
The S-1111B32MC-NYRTFU is a positive voltage regulator from the S-1111/1121 Series, manufactured by ABLIC Inc. It provides a fixed output voltage of 3.2 V with an accuracy of ±1.0%. The device supports an output current of up to 150 mA and operates within an input voltage range of 2.0 V to 6.5 V. It features a typical dropout voltage of 200 mV at 100 mA and a ripple rejection of 70 dB at 1.0 kHz. Current consumption is 35 μA during operation and 0.1 μA in power-off mode. The component is housed in an SOT-23-5 package and functions reliably across an ambient temperature range of -40°C to +85°C.
Feature Summary
- Built-in ON/OFF circuit enables significant reduction in current consumption for extended battery life
- Integrated overcurrent protection circuit limits load current to prevent damage to the output transistor
- Low on-resistance P-channel MOS FET output transistor ensures low dropout voltage performance
Applications
- Power supply for battery-powered devices
- Power supply for personal communication devices
- Power supply for home electric/electronic appliances
- Power supply for cellular phones
Procurement Notes
Verify the specific ordering suffix NYRTFU against official documentation to confirm pin configuration and environmental codes. Confirm compliance with lead-free and halogen-free requirements if specified. Check manufacturer notices regarding design status before procurement.
Selection Notes
Ensure the selected output capacitor has an ESR between 0.5 Ω and 5 Ω for stable operation. Tantalum capacitors are recommended. Verify that the application's power dissipation does not exceed the package limits under maximum load conditions.
Part Context
This component belongs to the S-1111/1121 Series of high ripple-rejection low dropout CMOS voltage regulators. The series utilizes CMOS technology to achieve low current consumption and high accuracy. The S-1111 variant features a specific pinout distinct from the S-1121 series.
Replacement Considerations

FAQ
What is the recommended type of output capacitor for this regulator?
A tantalum capacitor with a capacitance of 2.2 μF or more is recommended to ensure stable operation.
How does the ON/OFF pin function in the B-type product?
For the B-type product, setting the ON/OFF pin to a High level activates the regulator, while a Low level stops operation.
