Product Attributes

Introduction

The HT2785A is a high−performance linear regulator, offering a very wide operating input voltage range of up to 450 V DC, with an output current of up to 10 mA. Ideal for high input voltage applications such as industrial and home metering, home appliances. The HT2785A family offers ±5% initial accuracy, extremely high−power supply rejection ratio and ultra−low quiescent current. The HT2785A is optimized for high−voltage line and load transients, making this part ideal for harsh environment applications. The HT2785A is offered in fixed output voltage options 3.3 V, 5.0 V, 12 V and 15 V.
