A). This results in a noise free and sharp
breakdown knee.
APPLICATIONS
General regulation functions, where low noise at low
currents is required
Low power consumption applications
(e.g. hand-held applications).
DESCRIPTION
Low-power low noise voltage regulator diodes in SOD323
plastic SMD package.
The diodes are available in the normalized E24
5%
tolerance range. The series consists of 34 types with
nominal working voltages from 1.8 to 43 V.
