New Product Introduction

ON Semiconductor Low Dropout (LDO) Linear Voltage Regulators

Delivering LDO products in high performance, low power, small form factor solutions to enhance end products

ON Semiconductro IVN XCVR & ESD Protection products in different packages

ON Semiconductor's portfolio of Low Dropout (LDO) Linar Voltage regulators  can operate as precision current regulators providing highly stable and accurate voltages with low noise, high PSRR, low dropout, and a very low quiescent current consumption.They provide a wide range of input voltage options with fixed and adjustable output voltage. Available in single and dual output configuration.

In addition to their robust design and high reliability, the portfolio offers a variety of protections, making them virtually blow-out proof including overcurrent protection, overvoltage protection, overheat protection, and safe area compensation. Aside from a combination of ideal performance characteristics above, the portfolio is also offered in a variety of package sizes to match specific application requirements for applications such as industrial, consumer, portable & wireless (cameras, tablets, wireless handsets, and smartphones), IoT, and automotive.
