ABLIC S-19259 Voltage Regulators

Introduction

The ABLIC S-19259 Voltage Regulators are advanced positive voltage regulators designed for low voltage operations. With high accuracy and output current capabilities, these regulators are equipped with essential safety features, making them suitable for a variety of applications, particularly in automotive and home appliance sectors.

Part Description

The ABLIC S-19259 Voltage Regulators utilize CMOS technology to deliver reliable performance. They support a wide input voltage range of 1.5V to 5.5V and can be configured for output voltages ranging from 0.9V to 3.5V in 0.05V steps, or up to 5V using an external resistor. The regulators are designed with built-in overcurrent protection and thermal shutdown circuits, ensuring safe operation even under demanding conditions. A small ceramic capacitor (1µF) can be used for stability, and the low on-resistance of the built-in transistor results in a minimal dropout voltage, allowing for high output currents.
