Seiko Instruments Inc. (SII) releases several new voltage regulators to expand their already extensive voltage regulator lineup. SII’s leading edge technology solves the problem of improving battery life while substantially increasing product performance with a board space reduction of the power supply circuit. SII offers a complete product lineup that includes products with an output voltage accuracy of µ1.0%, current consumption of 9 μA and ripple rejection ratio of 80 dB, enabling longer battery life. These new voltage regulators also allow for the use of small ceramic capacitors and feature an ultra-small SNT package for high-density mounting. SII’s voltage regulators provide the leading edge technology required to help advance new product development.

Features of each New Product
•Output voltage accuracy of µ1.0%,
•Current consumption as low as 9 μA
•Ripple rejection ratio up to 80 dB
