ORDERING CODES
(*) Available in Tape & Reel with the suffix "-TR".
TEST CIRCUIT
ELECTRICAL CHARACTERISTICS OF L7905C (refer to the test circuits, TJ = 0 to 125°C, VI = -10V,
IO =500 mA, CI =2.2 µF, CO = 1 µF unless otherwise specified).
(*) Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account
separately. Pulse testing with low duty cycle is used.
