Overview
The S-1111B17MC-NYCTFG is a positive voltage regulator from the S-1111/1121 Series, manufactured by Seiko Instruments Inc. It utilizes CMOS technology to provide a fixed output voltage of 1.7 V with an accuracy of ±1.0%. The device features a low dropout voltage and high ripple rejection capabilities. It operates within an ambient temperature range of −40°C to +85°C and is housed in a compact SOT-23-5 package. The part includes built-in overcurrent protection and an ON/OFF control circuit for power management.
Feature Summary
- Built-in low on-resistance transistor enables low dropout voltage operation.
- Integrated overcurrent protection circuit limits output current to protect the load transistor.
- ON/OFF circuit allows for shutdown mode to minimize current consumption during power-off states.
- High ripple rejection capability ensures stable output voltage against input noise.
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 suffix codes against the manufacturer's datasheet to confirm pin configuration and environmental compliance. Ensure the ordering code matches the required output voltage and logic type for the ON/OFF pin. Confirm that the component source is authorized, as this series is marked not recommended for new design.
Selection Notes
Select this component when a fixed 1.7 V output is required with high accuracy. Consider the S-1111 series for its specific pinout configuration compared to the S-1121 series. Evaluate thermal dissipation requirements if operating near maximum current limits. Verify compatibility with external capacitor ESR values for stability.
Part Context
This part belongs to the S-1111/1121 Series of high ripple-rejection low dropout CMOS voltage regulators. The S-1111 variant differs from the S-1121 primarily in pin configuration. Both series share similar electrical characteristics but are distinct in physical layout for PCB integration.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material. Consult the manufacturer for direct replacements or compatible alternatives within the same product family.
FAQ
What is the logic type for the ON/OFF pin in the S-1111B17MC-NYCTFG?
The 'B' in the part number indicates positive logic for the ON/OFF pin, where a high signal turns the regulator on.
How does the NC pin function in the SOT-23-5 package?
The NC pin is electrically open but can be connected to the VIN or VSS pin if needed for mounting purposes.
