Product Summary

The L7809CV is a positive regulator. The L7809CV can provide local on-card regulation, eliminating thedistribution problems associated with single point regulation. If adequate heat sinking is provided,the L7809CV delivers over 1A output current.Although designed primarily as a fixed voltage regulator,the L7809CV can be used with external components to obtain adjustable voltage and currents.

Parametrics

L7809CV absolute maximum ratings: (1) DC Input Voltage Vi: 35V (for Vo=5 to 18V),o: 40V( for Vo=20, 24V) ; (2) Output Current Io: Internally Limited; (3) Power Dissipation Ptot: Internally Limited; (4) Storage Temperature Range Tstg: -65 to 150°C; (5) Operating Junction Temperature Range: 0 to 150°C.

Features

L7809CV features: (1) output current to 1.5A; (2) Output voltages of 5; 5.2; 6; 8; 8.5; 9; 10; 12; 15; 18; 24V; (3) thermal overload protection; (4) short circuit protection; (5) output transition SOA protection.
