Overview
The S-1111B16MC-NYBTFG is a positive fixed-output linear voltage regulator from the S-1111 Series. It provides a nominal output voltage of 1.6 V with an accuracy of ±1.0%. The device supports a maximum output current of 150 mA and features a typical dropout voltage of 200 mV at 100 mA. It operates within an input voltage range of 2.0 V to 6.5 V and includes built-in overcurrent protection. Current consumption is 35 µA during operation and 0.1 µA in power-off mode. Ripple rejection is typically 70 dB at 1.0 kHz.
Feature Summary
- Built-in ON/OFF circuit for significant power reduction
- High ripple rejection capability
- Low dropout voltage design
- Integrated overcurrent protection
Applications
- Power supply for battery-powered devices
- Power supply for personal communication devices
- Power supply for home electric/electronic appliances

Procurement Notes
Verify that the specific ordering suffix NYBTFG matches the required environmental code (U) for lead-free and halogen-free compliance. Confirm the pin configuration aligns with the S-1111 series layout, as it differs from the S-1121 series. Ensure the application circuit utilizes recommended output capacitors to maintain stability.
Selection Notes
Select this component when a fixed 1.6 V rail is required with high accuracy. Verify that the load current does not exceed 150 mA and that the package thermal dissipation limits are respected under maximum load conditions. Ensure the input voltage remains within the specified operational range.
Part Context
This part belongs to the S-1111/1121 Series of CMOS voltage regulators developed by Seiko Instruments Inc. The series is characterized by low dropout performance and high accuracy. The S-1111 variant specifically utilizes a pin configuration where Pin 1 is VIN and Pin 5 is VOUT.

FAQ
How does the ON/OFF pin function for the 'B' product type?
For the 'B' product type, the ON/OFF pin uses positive logic. A high-level input turns the regulator on, while a low-level input turns it off.
What is the recommended output capacitor for stable operation?
A tantalum capacitor of 2.2 µF or more is recommended to ensure stable operation by providing the necessary equivalent series resistance for phase compensation.
