FEATURES
•
Total power dissipation: max. 300 mW
•
Tolerance:
±5%
•
Working voltage range: nom. 2.4 to 15 V (E24 range)
•
Improved I
z
/V
z
characteristics 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 small
SOT23 plastic SMD packages.
The diodes are available in the normalized E24
±5%
tolerance range. The series consists of 20 types with
nominal working voltages from 2.4 to 15 V.
