Overview
The S-1111B36MC-NYVTFG is a positive fixed linear voltage regulator from the S-1111/1121 Series, manufactured by ABLIC Inc. It provides a nominal output voltage of 3.6 V with an accuracy of ±1.0%. The device supports an output current of up to 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 and an ON/OFF control circuit. The component is housed in a compact SOT-23-5 package.
Feature Summary
- Built-in low on-resistance P-channel MOS FET output transistor enables low dropout voltage operation.
- Integrated ON/OFF circuit allows for significant power reduction during standby states.
- Internal overcurrent protection circuit limits output current to prevent damage under fault conditions.
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 NYVTFG matches the required environmental code (U for lead-free/halogen-free) and product type (B for positive logic ON/OFF). Confirm the manufacturer designation as Seiko Instruments Inc. or ABLIC Inc., noting the series datasheet revision status. Ensure the component meets RoHS compliance requirements for the intended application environment.
Selection Notes
Select this part when a fixed 3.6 V rail is required with high accuracy. Ensure the load current does not exceed 150 mA while respecting package power dissipation limits. Use a tantalum output capacitor of at least 2.2 μF to maintain stability; ceramic capacitors may require a series resistor to provide sufficient equivalent series resistance.
Part Context
This component belongs to the S-1111/1121 Series of high ripple-rejection low dropout CMOS voltage regulators. The S-1111 variant utilizes a pin configuration where Pin 1 is VIN and Pin 5 is VOUT, distinguishing it from the S-1121 series which swaps these positions. The series is designed for portable electronics requiring efficient power management.

FAQ
What is the recommended output capacitor type for stable operation?
A tantalum capacitor with a capacitance of 2.2 μF or more is recommended to ensure stable operation due to its optimal equivalent series resistance characteristics.
How does the ON/OFF pin function for the 'B' product type?
For the 'B' product type, applying a High level turns the regulator ON, while applying a Low level turns it OFF, significantly reducing current consumption.
