Voltage regulator diodes
FEATURES
•
Total power dissipation: max. 300 mW
•
Tolerance:
±5%
•
Working voltage range: nom. 1.8 to 43 V (E24 range)
•
Improved I
Z
/V
Z
characteristic at low currents
(I
Z
= 50
µA).
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.
