PRELIMINARY INFORMATION
7A / 5A / 4.6A / 3A, FAST RESPONSE,
LOW DROPOUT POSITIVE LINEAR
VOLTAGE REGULATORS
TCL1584/1585/1587-04 6/6/97
TCL1584/1585/1587-04 6/6/97 TelCom Semiconductor reserves the right to make changes in the circuitry and specifications of its devices.
7A / 5A / 4.6A / 3A, FAST RESPONSE, LOW DROPOUT
POSITIVE LINEAR VOLTAGE REGULATORS
The TCL1584/1585/1587 are low dropout, positive lin-
ear voltage regulators. They have a maximum current
output specification of 7A, 5A, 4.6A and 3A respectively.
All three devices are supplied in fixed and adjustable output
voltage versions.
Good transient load response combined with low drop-
out voltage makes these devices ideal for the latest low
voltage microprocessor power supplies. Additionally, short-
circuit, thermal and safe operating area (SOA) protection is
provided internally to ensure reliable operation.
The TCL1587, TCL1585 and TCL1584 are available in
a 3-pin TO-220 tabbed power package and in a 3-pin surface
mount DDPAK-3 package.
