S-8357H42MC-NNBT2U

Overview

The S-8357H42MC-NNBT2U is a step-up switching regulator controller manufactured by ABLIC. It operates in the SOT-23-5 package and belongs to the S-8357 series. The device features a fixed output voltage of 4.2 V with a tolerance of 2%. It supports an output current of 100 mA and utilizes a PWM control method. The quiescent current is specified at 25.9 uA, and the switching frequency is 300 kHz. The maximum duty cycle is 78%. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrates low quiescent current operation for enhanced energy efficiency
Provides fixed output voltage regulation without external feedback resistors
Supports high output current capability for direct load driving

Applications

Battery-powered portable electronic devices
Low-power sensor node power supplies
IoT module voltage boosting

Procurement Notes

Verify the complete part number including suffixes against official ABLIC documentation to ensure correct voltage and package specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when a fixed 4.2 V output is required from a single-cell lithium battery source. Ensure the application input voltage remains below the regulated output level to enable proper step-up operation. Verify that the 100 mA output current meets the target load requirements.

Part Context

This part is a member of the S-8357 series of step-up switching regulators. It shares the SOT-23-5 package form factor with other variants in the family but differs in fixed output voltage settings. The series targets applications requiring compact power management solutions with minimal external component counts.
